A 2.00 kg mass is attached to a 3.00 m string and is raised at an angle of 45o relative to the rest position, as shown. Calculate the gravitational potential energy of the pendulum relative to its rest position. If the mass is released, determine its rest position. If the mass is released, determine its velocity when it reaches its rest position.
