Question

exploring collisions of objects on frictionless surfaces. You will answer the following questions.

When a moving object bounces elastically off an object initially at rest,

1. what happens to the total kinetic energy of the system?

2. what happens to the total momentum of the system?

3. how does the final velocity of the object that was initially moving depend on its mass, its initial velocity, and the total mass of the system?

4. how does the final velocity of the object that was initially at rest depend on the mass of the initially moving object, the initial velocity of the initially moving object, and the total mass of the system?

Explanation / Answer

1. remains same

2. remains same

3. v' = mv/M
4. v'' = Mv/m
