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 = −16t2 + vt + c. let h = 0. b. use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. round to the nearest tenth of a second.a. 0 = −16t2  + 99t  + 122;   8.4 sb. 0 = −16t2  + 99t  + 122;   0.7 sc. 0 = −16t2  + 122t  + 99;   8.4 sd. 0 = −16t2  + 122t  + 99;   0.7 s
