Two railroad freight cars with masses 110 Mg and 170Mg approach with equal speeds of 0.330 . They collide, the lighter car rebounding opposite its original direction at 0.270 m/s.

Find the velocity of the heavier car after the collision. Assume the original direction of the lighter car is positive.

What fraction of the original kinetic energy was lost in this inelastic collision?
