Question
A ball is dropped from a height of 11 feet and bounces. Suppose that each bounce is 7/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of
11()
= 9.625 feet, etc. (Assume g = 32ft/s and no air resistance.)
A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth time:
hn =
B. Find an expression for the total vertical distance the ball has traveled, in feet, when it hits the floor for the first, second, third and fourth times:
first time: D=
second time:D =
third time: D =
fourth time: D =
C. Find an expression, in closed form, for the total vertical distance the ball has traveled when it hits the floor for the nth time.
Dn =
