Blocks A (mass 2.00 kg) and B (mass 15.00 kg) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 10.0 m/s. The blocks are equipped with ideal spring bumpers. The collision is head-on, so all motion before and after the collision is along a straight line. Let +x be the direction of the initial motion of A.
Find the maximum energy stored in the spring bumpers and the velocity of each block at that time.
Find the velocity of each block after they have moved apart.
