You can put this solution on YOUR website! The height of a projectile fired upward with an initial velocity of 400 feet per second is given by the formula h=-16t^2+400t, where h is the height in feet and t is the time in seconds. FIND the time required for return
---------------
At "return," or impact, h(t) = 0
h=-16t^2+400t = 0
Solve for t.
There are 2 values, one for launch, one for impact.
