Blocks ?A ?(mass 2.00 kg) and ?B ?(mass 10.00 kg) move on a frictionless, horizontal surface. Initially, block ?B ?is at rest and block ?A ?is moving toward it at 2.00 m/s. The blocks are equipped with ideal spring bumpers, as in Example 8.10 (Section 8.4). The collision is head-on, so all motion before and after the collision is along a straight line. (a) Find the maximum energy stored in the spring bumpers and the velocity of each block at that time. (b) Find the velocity of each block after they have moved apart.

Solution to 47E Step 1 Mass of the block A=2 kg Mass of the block B=10 kg Initial velocity of A =2m/s Initial velocity of B =0m/s
