Problem
A pendulum consists of a ball with a mass of attached to the ceiling by a massless rope. The ball is released from rest at some initial angle from vertical and freely swings back and forth. The free body diagram of the ball when the pendulum makes an angle of from the vertical and has a tension of in the rope is shown below.
Calculate the speed of the mass when rope at this point.
Write your answer to significant figures.
