Apendulum has 760 j of potential energy at its highest point of it swing how much kinetic energy will it have at the bottom of it swing

At its highest point (Point A) the pendulum is momentarily motionless. All of the energy in the pendulum is gravitational potential energy and there is no kinetic energy. At the lowest point (Point D) the pendulum has its greatest speed. All of the energy in the pendulum is kinetic energy and there is no gravitational potential energy
