find the time,t, in seconds that it takes an object dropped from a height of 784 feet to reach the ground. use the function h=-16t^2+784

OpenStudy (mertsj):

We want the time when the height is 0 since the object is on the ground. So set h = 0 and solve for t

OpenStudy (mertsj):

\[-16t^2=-784\] \[t^2=49\] \[t=7\]
