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?

6) Consider an atomic nucleus that's moving at a speed of 500m/s. This nucleus emits an alpha particle (=nucleus of a Helium atom) in the direction of its velocity, and the new nucleus (produced by the emission of the alpha particle) slows to 450m/s. If the alpha particle has a mass of 4u and the original nucleus has a mass of 208u, what speed does the alpha particle have when it is emitted? (Here u is the atomic mass unit. You could take for u the value of the proton mass, i.e. u= m, = 1.67 × 10-27kg.)
