The height of a projectile (in feet) is modeled by h(t) = -16t+ vt + h, where v, is the initial vertical velocity (in feet per
second) and h, is the initial height (in feet). If a shell leaves a cannon at ground level going straight up at 800 ft/sec, when is
the shell at a height of 3600 ft?
O at 45 sec
at 5 sec and 45 sec
