A ball rebounds to a height of 30.0 cm on the third bounce and to a height of 5.2 cm on the sixth bounce.
a. Write two different yet equivalent equations in point-ratio form, y = y1 (bx-x1 using r for the ratio. Let x represent the bounce number, and let y represent the rebound height in centimeters.
b. Set the two equations equal to each other. Solve for r.
c. What height was the ball dropped from?
