A ball is dropped from a height of 10 feet and bounces. Each bounce is 3/4 of the height
Chapter 13, Problem 21(choose chapter or problem)
A ball is dropped from a height of 10 feet and bounces. Each bounce is 3/4 of the height of the bounce before. Thus after the ball hits the floor for the first time, the ball rises to a height of 10(3/4) = 7.5 feet, and after it hits the floor for the second time, it rises to a height of 7.5(3/4) = 10(3/4)2 = 5.625 feet. (a) Find an expression for the height to which the ball rises after it hits the floor for the nth time. (b) Find an expression for the total vertical distance the ball has traveled when it hits the floor for the first, second, third, and fourth times. (c) Find an expression for the total vertical distance the ball has traveled when it hits the floor for the nth time. Express your answer in closed form.
