Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth.
a rocket is launched from atop a 101-foot cliff with an initial velocity of 116 ft/s.
a. substitute the values into the vertical motion formula h=-16t^2+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.
