9. A rocket is launched from the top of a 76-foot cliff with an initial velocity of 135 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.

A. 0 = –16t2 + 135t + 76; 0.5 s

B. 0 = –16t2 + 76t + 135; 9 s

C. 0 = –16t2 + 76t + 135; 0.5 s

D. 0 = –16t2 + 135t + 76; 9 s
