PHYSICS (KINETIC ENERGY and COEFFICIENT OF RESTITUTION) Help PHYSICS WIZARDS! THANKS!?
A 1-lb rubber ball bounces down a flight of stairs, striking each step in turn and rebounding to the height of the step above. If the height of each step is 1 ft, find the coefficient of restitution. What is the maximum kinetic energy if the ball?
