Two railroad freight cars with masses 100 Mg and 150 Mg approachwith equal speeds of 0.330 m/s. They collide, the lighter carrebounding opposite its original direction at 0.280 m/s.
1) Find the velocity of the heavier car after the collision. Assumethe original direction of the lighter car is positive.
2)What fraction of the original kinetic energy was lost in thisinelastic collision?
