Add FBD if needed please Ty

Block A (mass 12.00 kg) and B (mass 3.00 kg) move on a frictionless, horizontal surface. Initially, block A is moving toward B at 4.00 m/s, and block B moves toward lock A at 2.0 m/s. The blocks are equipped with ideal spring bumpers, The collision is head-on, so all motion before and after the collision is alonga 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 moved apart. VA = 4.0 m/s Va = 20m/s A WWW
