Question

a punter kicked the football into the air with an upward velocity of 62 ft/s. its height in feet after t seconds is given by the function h = -16t^2 + 62t +2. What is the maximum height the ball reaches? How long will it take the football to reach the maximum height? How long does it take for the ball to hit the ground?

Answer 1

t = -B/2A = -62/-32 = 1.94

h = -16*1.94^2 + 62*1.94 + 2 = 62.1 Ft.

Answer 2

b. T = Tr + Tf = 1.94 + 1.94 = 3.88 s.

Tr = Rise time.
Tf = Fall time.

Answer 3

The answer is B. 1.94 s, 62.06
