A rocket is launched from atop a 105-foot cliff with an initial velocity of 156ft/s. the height of the rocket above the ground at time t is given by

h= -16t^2 + 156t + 105. When will the

rocket hit the ground after it is launched? Round to the nearest second.

(My answer is 10.4 s ??)

no need to ask, plug back in

h = -16(10.4)^2 + 156(10.4) +105

= -1730.56 + 1622.4 + 105

= -1730.56 + 1727.4
close enough to the ground :)
