Blocks A (mass 5.00 kg ) and B (mass 6.50 kg ) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving 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. Let +x be the direction of the initial motion of block A. Questions:
A) Find the maximum energy stored in the spring bumpers.
B) Find the velocity of block A when the energy stored in the spring bumpers is maximum.
C) Find the velocity of block B when the energy stored in the spring bumpers is maximum.
D) Find the velocity of block A after they have moved apart.
E) Find the velocity of B after they have moved apart.
