Physics

Particle A and particle B are held togetherwith a compressed spring between them. When they are released, thespring pushes them apart and they then fly off in oppositedirections, free of the spring. The mass of A is 2.00times the mass of B, and the energy stored in the springwas 50 J. Assume that the spring has negligible mass and that allits stored energy is transferred to the particles. Once thattransfer is complete, what are the kinetic energies of(a) particle A and (b)particle B?
