4. Block A and block B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they fly off in opposite directions, free of the spring. The mass of A is twice the mass of B, and the energy stored in the spring was 60 J. Assume that the spring has negligible mass and that all of its energy is transferred to the blocks. Once that transfer is complete, what are the kinetic energies of (a) block A and (b) block B?
