A 5.00 kg object, object A, moving at 5.50m/s to the right collides head on with a 3.50kg object, object B, that is a rest. The 5.00kg object ends up with the speed of 1.50m/s in the opposite direction. (a) what is velocity of the two objects after collision? (b) How much kinetic energy is transferred to object B during the collision?
