A pendulum consisting of a small heavy ball of mass m at the end of a string of length L is released from a horizontal position. When the ball is at point P, the string forms an angle of θ with the horizontal as shown.
(a) In the space below, draw a force diagram showing all of the forces acting on the ball at P. Identify each force clearly.
(b) Determine the speed of the ball at P.
(c) Determine the tension in the string when the ball is at P.
