6. Physicists tell us that altitude h in feet of a projectile t seconds after firing is h=-16+v+h, where v, is the initial velocity in feet per second and h, is the altitude in feet from which it is fired. If a rocket is launched from a hilltop 2400 feet above the desert with an initial upward velocity of 400 feet per second, then when will it land on the desert?
