When a ball is thrown vertically upward, the height s reached varies directly as the square of the speed v with which the ball is thrown.
A ball thrown with a speed of 40 feet per second reaches a height of 25 feet. Find the EXACT height reached when the ball is thrown with a speed of 60 feet per second.
---------------
60/40 = 1.5 times the speed
1.5^2 = 2.25
2.25*25 = 56.25 feet
