Mass m = 0,1 kg moves to the right with speed v = 0.39 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.63 of its original kinetic energy. What is the speed VR (in m/s) of the mass which was originally at rest before the collision?
