speed speed speed speed =V =0 =VL =VR Mass m = 0.1 kg moves to the right with speed v = 0.41 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.71 of its original kinetic energy. What is the speed VR (in m/s) of the mass which was originally at rest before the collision? Hints: All motion is in 1D. Ignore friction between the masses and the horizontal surface. You will probably need to use the quadratic formula to solve the resulting equations. VR must be greater than VL since the masses can't pass through each other
