Question 211164: The height of an object tossed upward with an initial velocity of 104 feet per second is given by the formula h = -16t^2 + 104 t, where h is the height in feet and t is the time in seconds. Find the time required for the object to return to its point of departure
Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
You are trying to find the time, t, at which the height, h, of the object is zero (initial height) again. I say again because it starts out at h = 0.
So you set h = 0 and solve for t.
Factor t from the left side.
So...
(Initial condition) or:
and...
Divide both sides by -16.
seconds.
The oject returns to its point of departure in 6.5 seonds.
