1.	Consider the roller coaster in the figure beside.The car starts at position A with an initial height,hA = 20 m and speed vA = 15 m s-1. Finda) the speed of the roller coaster when itreaches the top of the track at position B,where hB = 25 m, and [11.26 m s-1]b) the speed of the roller coaster when itreaches the bottom of the track. [24.85 m s-1]
Answer» Answer: A 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.
