Suppose that the kicker for the chargers has a punt that can be modeled by h(t)=-2t^2+200, where its height from the ground can be found based on how many seconds (t) have passed since the kick. Given this how long will it take for the foot ball to hit the ground?
P.s. I can figure out to type in exponents so the 2t^2 is supposed to be 2t squared

Solution

h(t)=-2t^2+200
--------------
At t = 0, the ball is 200 feet up?
I think it\'s
h(t)=-2t^2+200t
----------------
It hits the ground when h(t) = 0
h(t)=-2t^2+200t = 0
2t^2 = 200t
t = 0 (at the start)
t = 100 (at impact)
