A $fifty \mathrm{~one thousand}$ ball of clay traveling at speed $v_{i}$ hits and sticks to a $1.0 \mathrm{~kg}$ block sitting at residuum on a frictionless surface. a. What is the speed of the block after the collision? b. Prove that the mechanical energy is not conserved in this collision. What percent of the ball's initial kinetic free energy is "lost"? Where did this kinetic energy get?

How-do-you-do, everyone. This is a problem Based on concept of head on collision Here it is given mass of callable 50 g. That is 0.v kg moving with the speed up. Oh, six.five m per 2d. Mass of the block is one kg and initially it is addressed. Contribution of applying contribution of linear meter. Mm, yep. Mhm. Aye, yep. Mhm. A month into the fiver plus m two v i to his car to Yemen plus m 2 into the final considering after collision, believe all is strict with the block. And then information technology is too big. Okay, 0.5 kg into half dozen.5 plus nada is cut off. Why am 05 plus ane? So finding where the city you will become mhm. Aye. Why 31 m per second? Yes, More. Yeah. No, nosotros role initial kind of technology is Mm B I one described. And that'south how I am too. Nosotros have to square that is how 505 to half dozen.five. Holy square. So it is to be 1.56 Who? V Children. I find that kind of technology. How and 1 plus g two in to be final respect. One plus bespeak due to v. Uh huh. 1231 square. So it's just a calendar week. What do you lot know? Five tooth percentage loss of kind of applied science. Any ship minus If I did information technology upon Anisha in 200 substitute that I do Initial is 1.56 to 5, minus 50.55 upon 0.55 and two 100 on solving information technology. If nosotros will get 95.22% that's what. Thanks for watching it.

Trouble. We're going to talk nearly conservation off moment. And so showtime, remember that the momentum of a particle is able to x mass times its velocity, and also that the full went off of a organization is conserved, meaning that the initial mental system is equal to the last women's and the initial momentum music, which is the sum of the initial momentum off the individual particles while the last momentum is equal to the sum of the individual Momenta off each particle. Also, we need to remember how we summate impulse and what we need is that the impulse can be calculated either as the average force times the time forth which of force was practical over an object or every bit the change in momentum them s. And so what we take in our problem is a ball of dirt that has a mass off 20 m and is has an initial velocity off xxx m percent, um, mhm and hit and the brawl clay hits block that has a mass off i kg that is a chest okay and are going question A is to detect what is the final speed of the ensemble brawl dirt plus block after the ball claim sticks to the cake. So permit'due south correct, permit's use conservation of momentum. The initial momentum of the ball of clay is the mass of the ball clay times the speed and the block does not have any momentum because its speed is equal to cipher. And this is equal to the mass of the ball clay, plus the mass of the block times the speed V. Okay, so Five that's the speed off the to off the end get together is equal to M. C. Times we see the value by embassy pleasant beingness So this is the mass of clay off 0.2 kg times. Uh, we see that'south thirty kg 30 grand per second. I'm sorry, divided past ane point one-time to kill a wimps, and this is equal to zero point 59 meters per 2d. So in question, be are going to calculate, um, what is the impulse that the clay exerts over the cake? And so find that the clay let's say it's moving in this direction. I'm going to phone call the positive management, and so it hits the block and the cake starts moving. And then notice that the final woman's um of the block is one kg times is your 0.59 m per 2d and the initial momentum is simply zero because the block is a chest. Then the impulse that is the difference in Momenta is equal to 0.59 kilograms meters per second. This is the impulse that the clay exerts over the law questions See, we have to summate the impulse that the cake exerts over the clay. So there is that the initial moment or the dirt is equal to the mass of the clays zero point yous would shoot kilograms times the speed of the clay of 30 m pct per 2d. Eso this is zero points half dozen kilograms meters 2d and the terminal momentum is equal to 0.two kg times zip point 59 meters per second. Yeah, this is approximately 0.1 kilograms meters per second. So the alter in momentum that is pf prime number on SP I prime is mine a 0.59 kg meters per second Mhm and this is the answer to elation Seat in question D. Nosotros accept to check whether or non the momentum Uh, I'm using the letter. I am only gonna be consequent with it. The impulse, Um, that's the cake exerts on the clay. So I'm gonna call it BC is equal to minus the impulse that the clay exerts on the block and the respond is yes. And this is due basically to Newton'due south tertiary law. It tells us that every action has an equal and reverse reaction. Eso the magnitude of the impulses must exist the aforementioned considering the magnitude of the forces that are the same and of course they are in contact during the same period of time and it must be opposite. And so there's That's why there's a minus sign which concludes our problem.

Okay, and then in question A, the total momentum is equal. K one nosotros want pastime to be to chiliad. Y is the mass for the kickoff father clay which is xx brands you become where the kilograms is about 0.2 kilograms we desire is the speed or the velocity for the offset ball which givens 12 meters per second. M two is the mass for the 2d bottle claim which is 40 grapes. The recovery two kilograms, 0.four killed webs nosotros two is the speed all of final yr for the second ball. Dirt, you should exist glad zero because he was arrested. And then therefore the strong determined a total momentum off the friend s in a friend asked. Okay, then therefore he is equal to 0.2 kilograms times 12 meters per second plus 0.iv kilograms times practise a meter per 2d and this will give the states That's all. The momentum of the system is nigh naught point, um 24 que Laguerre meter per second. And for the side by side quite next question. Well, we know that in friend as prime, the total momentum is equal nothing, which is people here? Then therefore, the velocity equals naught as well, Considering the mass never equal nil. Okay. And for questions, See, while this the terminal e um, off the resulting threescore grand, Bob Clay should be zilch because the total momentum was equal. Full general. Ok, and for the last question D here. Then co-ordinate toa conservation police off the momentum and what we want Plus, MTV two should be, um, won class and me to be okay because somewhen listed stick together. It'south a careful will have the final speed here, which is exist equal to m one. We want united states and to be to over thou ane plus empty. So we know the mass for each ball and the speed football so that nosotros can determine the final velocity, which is equal to zilch point nothing to kill. Wears times 12 meters per 2d plus 0.iv kilograms times Bring together me for a second over 0.2 Give a wears plus 0.four kilograms. Okay. And this volition requite united states the final terminal twelvemonth, which is the post collision. We lost the over 60 grand ball. The clay in reference French republic, see uh, friend s. Which is? Ah, people to full meter for a 2nd. And since it'southward positive, that ways the management off the blasting should be people Jupiter, whether rights Because along positive X axis. Okay, so, to all the rights and this is my answer for this question

Howdy, I forbid This is the problem Based on head on collision here information technology is given initial velocity of the wall is 30 thou per second mass of all its continuum or 102 kg initial velocity of a cake null Mara Sov bloc is Valle Katie. Nosotros have to find the concluding velocity of the system. So applying contribution of momentum that finally we have to find the system becomes well applying Conservation of momentum initial momentum to be its final momentum. Mass of what? Initial velocity of what Massa block into initial velocity of block. He'due south got to Mars, of course. Plus Master block into final velocity. Substitute the video. This is 0.0 toe into right 30 one in 20 10 to plus ane until the final. And so final velocity you volition get 0.588 m per 2d. Yeah. Oh, this is a office. A not part we Now nosotros have to calculate impulse on the block Impulse on the block will be change of momentum of block that is mass a block velocity of block Finally massive blob into velocity of block. Initially, initially it was addressed 1 and 2.5 eighteen minus zip. And then it is 00.588 Newton. Mm, yeah. Mhm. Uh huh. Impulse on the brawl clip. Yeah. Change of momentum. Mass of Global into its supply. The speed myself label into its initial velocity 0.two and two.588 minus 102 in 2. 30. So it is to be yes, minus 0.588 Newton's second is impulse of ball is called to impulse. A block is called to impulse of the level that's so
