58) A puck with a mass m1 50 g moving at 1.0 m/s approaches a stationary puck with a mass m2 100 g on a frictionless air table, and they undergo a sudden two-dimensional elastic collision. After the collision, both pucks have identical speeds, but travel in different directions. What is the angle between the original...
