In elastic collisions (a) Momentum is conserved (b) KE is conserved (c) Both momentum and $\mathrm{KE}$ are conserved (d) Momentum not conserved but $\mathrm{KE}$ is conserved

All right for this question. I got a little simulation online to show you. So I have object. Want an object to They're gonna crash into each other and here I can change the elasticity of it. So let's see what happens whenever it's perfectly elastic. So whenever I mean, I say elastic. I mean, it's like bouncy and an elastic is like sticky. So here I play it. It's elastic. They bounce off. I'll do when it's an elastic and now it's sticky. Okay, so anyways, let's see what happens to the kinetic energy when it's perfectly elastic. As you see, the kinetic energy doesn't change. It's 0.25 okay? And it doesn't matter what the masses of the objects are. So let's change the massive object one. So it's two in the object to switch three. OK, now the kinetic energy is one. Ah, play. It doesn't matter. The kinetic energy is ah conserved. Now look at the moment, um, down here. So the mo mentum is going to be, too. And whenever I play simulation, it still adds up to exactly two. So the kinetic energy is conserved and the Mo mentum is conserved. But now Let's make it not perfectly elastic. So now it's a little sticky. Okay, it's a little in elastic. It's no longer perfectly in a elastic collision. So let's see what happens sticking again and energy. Let's see what happens to the momentum. So I play it after the collision. Look, you lost some of the kinetic energy, Actually, quite a bit. You lost almost half, but the Mo mentum still adds up to exactly two. So, as you see, the kinetic energy is not conserved, But the moment, um, is conserved.

So her in this problem were given that two objects move towards each other, the collide and then separate on were also given that the net external force acting on the object is zero on the kind of energies also lost in the collision. So this is lost energy is lost Now there are four options given and we're total that which option is correct now since the Net force acting on the object is zero. So the total leaner moment of will be conserved so we can contribute by this that linear momentum will be conserved next. They are saying that kinetic energy is lost during the collision. So the collision cannot be elastic collision. It has to be non elastic, so collision is not elastic. Option C matches with the given statement. Therefore we can conclude that options C is correct. I hope you have understood problem. Thank you

So in this problem we know that we have two objects they're moving and the decline and that separates. But we know that the searching ah, certain amount off kinetic energy is lost. So in that sense, we know that the energy is not conservatives process. So this is a elastic process. Yeah, and ah, no matter it is elastic or elastic. Process. The Mo mentum is always conserved in this ah collision problem. So momentum is conserved all right?

We have a perfectly elastic collision. And with elastic collision we can apply the conservation of momentum and the conservation of of mechanical energy. So going down this list, we have to choose. You have a false yeah. For part it says the total mechanical energy is conserved. This is true for an elastic collision. For part B says the total Connecticut energy is conserved. This is also true, and for C it says the total momentum is conserved. This is also true. However. For part D. It says the momentum of each object is conserved, and the key word here would be each object. And in this case for any collision in elastic or elastic, we can't say that the object of each object, the momentum of each object is going to be conserved. Therefore D is false as well as E. We cannot say that the kinetic energy of each object is conserved given that during a collision we sometimes have a transfer of energy from one object to the next. So here we have a B. C. Being true. Dnd being false. That is the end of the solution. Thank you for watching
