Chapter 8, Problem 85GP

A ball is attached to a horizontal cord of length ℓ whose other end is fixed, Fig. 8–42. (a) If the ball is released, what will be its speed at the lowest point of its path? (b) A peg is located a distance h directly below the point of attachment of the cord. If h = 0.80 l , what will be the speed of the ball when it reaches the top of its circular path about the peg?
