The string in the figure is L- 120 cm long, has a ball attached topne end, and is fixed at its other end. The distance d from the fixed end to a fixed peg at point Pis 74 cm. When the initially stationary Ball is released with the string horizontal as shown, it will swing along the dashed arc. What is its speed when it reaches (a) its lowest point and (b) its highest point after the string catches on the peg? (a) Number Units (b) Number Units
