ME7.6 Pendulum Suspended from Ceiling

This pendulum is suspended from the ceiling with long rope already attached to the first pillar on the right facing the class. A student volunteer feels the weight of the ball, then attaches it to the rope. He stands by the pillar and put the ball on his nose. Then he lets go and remains in place. From his point of view, he will be hit in the face with the ball, but conservation of energy says that the ball will go no closer to his nose than it was when he let go.
