1. The problem statement, all variables and given/known data 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 5.00 times the mass of B, and the energy stored in the spring was 111 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle? 2. Relevant equations mass of particle A = 5 times mass of particle B KE(before) = KE(after) (1/2)mv^2 = (1/2)mv^2 The sum of KE(before and after) = 111J 3. The attempt at a solution (1/2)mv^2 + (1/2)mv^2 = 111J mv^2 + mv^2 = 222J 5(mass of A)v^2 + (mass of B)v^2 = 222J and I'm not sure how I can find the individual masses from there any suggestions on how I might be able to do that?
