20 cm The string in figure is L = 120 cm long, has a ball attached to one end, and is fixed its other end. The distance d to the fixed peg at point P is 75.0 cm. When the initially stationary ball is released d=75 cm with the string horizontal as shown, it will swing along the dashed arc. What is the speed when it reaches its highest point after the string catches on the peg ? (Solve by using the energy methods):
