1. A simple pendulum is made from a 0.773-m-long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed? 2. f = 1/2pi (g/l)^1/2 3. I thought that maximum speed would be when the string is vertical for the first time. This would be when the pendulm had gone through 1/4 of a full oscillation. So I calculated f =.567s and 1/4 f = .142s, But this is wrong, Am I on the right track or way off?
