A stone is dropped from a height of h1 = 3.55 m above the ground. After it bounces, it only makes it to a height h2 = 2.37 m above the ground. The stone has mass m = 0.148 kg.  a) What is the magnitude of the impulse I, in kilogram meters per second, the stone experienced during the bounce?   b)  If the stone was in contact with the ground for t = 0.153 s, what was the magnitude of the constant force F acting on it, in newtons?   c) How much energy, in joules, did the stone transfer to the environment during the bounce?
