A kicker kicks a football toward the opponent's goal line during a game. The ball begins its flight with an initial velocity of 100 feet per second when it is kicked at a height of 3 feet by the kicker. To the nearest foot, what maximum height will the ball reach?

You may use the function:
h(t)=-16y^2+100t+3
100 feet
129 feet
159 feet
The answer cannot be determined

take the derivative and find a local max

anonymous · Answer

oops its -16t^2

anonymous · Answer

does that make sense?
