A 61.0-g ball traveling at 6.3 m/s is caught by a 220-g pendulum bob. The center of mass of the pendulum / ball system reaches a maximum height of 10.4 cm (relative to the initial res position) after the collision. Calculate: a. The initial kinetic energy of the ball (Kball). b. The gravitational potential energy of the pendulum/ball system at the end (Ug). The kinetic energy of the pendulum/ball system in the instant after the collision (Kball+bob) Use L=30.2 cm and R=26.3cm. d. The efficiency of the collision(& collision e. The efficiency of the pendulum (&). To m T
