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?

Question Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 7.00 times the mass of B, and the energy stored in the spring was 88 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Part (a) Once that transfer is complete, what is the kinetic energy of particle A? Part (b) (b) Once that transfer is complete, what is the kinetic energy of particle B?
