A ball of mass 0.7 kg is dropped vertically from a height of 10 m onto a concrete floor. The ball is observed to bounce a number of times before coming to rest. The coefficient of restitution for the ball hitting the floor is 0.85;
a) Recognize and state the different types of Energy that are significant in determining the outcome of this experiment.
b) What is the total mechanical energy that the system begins with?
c) What will the velocity of the ball be instantly before it strikes the ground for the first time?
d) What is the total mechanical energy of the system directly after the balls first bounce?
e) To what height will the ball rebound after the first bounce?
f) How many times will the ball bounce?
