Name

Was the collision between the ball and pendulum elastic or inelastic? Explain, and then justify your answer by calculating the absolute K$.$E$.$ loss, if any, which occurred when the ball collided with the pendulum. Show your work.

Using information from Question $2,$ calculate the fractional K$.$E$.$ loss, if any, during the collision $($i$.$e$.$ express the loss as a percent$).$ Show your work.

Explain what became of the K$.$E$.$ "lost" during the collision. What other forms did it change to$,$ exactly where in the apparatus did these changes occur, and where did the energy go$?$
