Blocks A (mass 4.00 kg ) and B (mass 6.00 kg ) move on africtionless, horizontal surface. Initially, block B is at rest andblock A is moving toward it at 5.00 m/s . The blocks are equippedwith ideal spring bumpers. The collision is head-on, so all motionbefore and after the collision is along a straight line. Let +x bethe direction of the initial motion of block A. Find the maximumenergy stored in the spring bumpers. Find the velocity of block Awhen the energy stored in the spring bumpers is maximum. Find thevelocity of block B when the energy stored in the spring bumpers ismaximum. Find the velocity of block A after they have moved apart.Find the velocity of B after they have moved apart.
