A 1-kg metal ball slides across an incredibly smooth table at 5 m/s and hits a 0.2-kg metal ball at rest. After the collision both move off in the same direction as the original ball, with the 1-kg ball moving at 0.1 m/s and the 0.2-kg ball moving at 24.5 m/s. The system is the two balls. What can be said about this collision? Since the total momentum of the system is constant both before and after the collision, this is a realistic collision The total momentum of the system is constant before and after the collision but since the total kinetic energy increases, this is an unrealistic collision Since the total kinetic energy of the system is constant both before and after the collision, this is a realistic collision. The total momentum of the system is constant before and after the collision but since the total kinetic energy changes, this is an unrealistic collision
