A Missile fired straight up in to the air has the height, in feet, given by h=-16t^2+32t, where t is time, in seconds, the missile been in the air.
By setting up and solving the equation find the time when the missile hits the ground
--------------
h(t) = -16t^2+32t
Find when h(t) = 0 (that's when it's on the ground)
There are 2 values, one at launch, one at impact.
-------------
PS That's not a missile, it's a projectile. Missiles have thrust.
