When an object is launched into the air, it’s height (in feet) above the ground is given by h = vt - 16t^2 where t is seconds after the launch and v is the object’s initial upward velocity in ft/sec. A gun is fired in the air and the bullet's initial velocity is approximately 3,000 ft./sec. How long will it take the bullet to come back to the ground assuming there is no interference with it's path?
