Practice on Motion

A group of students are carried to the top of a drop tower ride at an amusement park. Suddenly the chair drops straight down the tower track. The brakes slow their motion as they approach the ground. Describe the changes in their motion and how their energy transfers from their position at the top of the ride to the bottom.
