66. First, we find the speed v of the ball of mass m 1 right before the collision (just as it reaches its lowest point of swing). Mechanical energy conservation (with h = 0.700 m) leads to 2 11 1 2 3.7 m s. 2 mgh mv v gh = ¡ == (a) We now treat the elastic collision using Eq. 9-67: 12 1 0.5 kg 2.5 kg
