Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth.
a rocket is launched from atop a 76-foot cliff with an initial velocity of 135 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.
1.)0= -16t^2 + 135t + 76; 0.5 s
2.)0= -16t^2 + 135t + 76; 9 s
