Blocks A (mass 6.50 kilogram) and B (mass 12 kilogram) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 3 meter per second. The blocks are equipped with ideal spring bumpers. The collision is head-on, therefore all motion before and after the collision is along a straight line. Let +x be the direction of the initial motion of A,
Part A. Determine the maximum energy stored in the spring bumpers and the velocity of each block at that time.
Part B. Determine the velocity of each block after they have moved apart.
