Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. A rocket is launched from atop a 99-foot cliff with an initial velocity of 122 ft/s. a. Substitute the values into the vertical motion formula h=-16^2+vt+c. Let h = 0. b. Use the quadratic formula to find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.
