Blocks A (5.00 kg) and B (10.00 kg) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is mov
ing toward it at 4.00 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. What is the maximum energy stored in the spring bumpers during the collision process
