Physics

A pendulum consists of a sphere of mass 1.5 kg attached to a light cord of length 10.9 m as in the figure below. The sphere is released from rest when the cord makes a 58 degree angle with the vertical, and the pivot at P is frictionless. The acceleration of gravity is 9.8 m/s^2 . Find the speed of the sphere when it is at the lowest point. Answer in units of m/s
What is the tension in the cord?
