A kicker kicks a football toward the opponent's goal line during a game. The ball begins its flight with an initial velocity of 70 feet per second when it is kicked at a height of 2 feet by the kicker. To the nearest foot, what maximum height will the ball reach?

You may use the function:
h(t)=-16t^2+70t+2
A. The answer cannot be determined.
B. 79 feet
C. 981 feet
D. 129 feet

  		A. 	The answer cannot be determined.
  		B. 	79 feet
  		C. 	981 feet
  		D. 	129 feet

anonymous · Answer

-16t^2 + 70t + 2
-b/2a gives maximum height
-70/-32
f(70/32) = 79
B. 79 Feet
