A rocket is launched from the top of a 99-foot cliff with an initial velocity of 122 ft/s. a. Substitute the values into the vertical motion formula h = –16t2 + 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. 0=-16t^2+122t+99; 0.7s
0=-16t^2+99t+122; 8.4s
0=-16t^2+99t+122; 0.7s
0=-16t^2+122t+99; 8.4s
