Question 10

A cricket ball has 54 J of kinetic energy immediately before it hits a tightly stretched practice net. The ball and the net deform until the ball is momentarily stationary. By this moment, 17 J has been transferred to stores other than the elastic stores of the ball and the net. What is the total increase in the elastic energy stores of the ball and the net?
