Perform the analysis for energy and momentum as before. using the quasi-analytical rotational inertia from the previous question, calculate the angular kinetic energy of the ball before the collision, and the angular kinetic energy of the pendulum system after the collision using equations 5, 6, and 11.  what is the kinetic energy of the ball immediately after the collision? why?  is this a perfectly elastic collision? what is the percentage of the kinetic energy lost (converted to thermal energy) during the collision?
