A ball is dropped from the top of a building that is 250 feet tall. The height h of the ball in feet after t seconds is modeled by the function h = -16t2 +250. How long will it take for the ball to reach the ground? Round your answer to the nearest hundredth if necessary.

Question

anonymous · Answer

h(t) = 0
0 = -16t^2 + 250           
16t^2 = 250
/16         /16
t^2 = 15.625
square root t and 15.625
T= 3.953 Seconds

how do i verify my answer?

anonymous · Answer

Plug your answer (3.953) back into the equation and solve for H(t) to verify that it comes out to 0.
