Cart A, of mass 3.00 kg, approaches and collides with cart B, which has a mass of 7.00 kg and is initially at rest.
When the springs have reached their maximum compression,
a. cart A has come to rest relative to the ground.
b. both carts have the same velocity.
c. both carts have the same momentum.
d. all the initial kinetic energy of cart A has been converted to elastic potential energy.
Now I am not going to answer any more of these. You can figure this out.
