If the ball bounces back 12 times from the 1.5 m height, which of the following is a possibility for how many times the ball bounces from a 1 m height?

8 times because the ball will have more mechanical energy
15 times because the ball will have less mechanical energy
8 times because the ball will have less mechanical energy
15 times because the ball will have more mechanical energy
