Determine the coefficient of friction between a ball bearing and a roller coaster if the roller coaster starts with an 12.02 g ball being dropped from a height of 1.55 m (ignore friction during drop), and finishes the 6.15 m track along the floor with a speed of 4.2 m/s.

Answer:
roller coaster ride is a thrilling experience which involves a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor (or other mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation
