6. A rocket is launched from atop a 68-foot cliff with an initial velocity of 155 ft/s. The height of the rocket above the ground at time t is given by h = –16t2 + 155t + 68. When will the rocket hit the ground after it is launched? Round to the nearest tenth of a second.

    Hint: Since h represents the height of the rocket, set h = 0, then solve for t.

    So solve 0 = –16t^2 + 155t + 68

    Basically, that means you don't know how to factor a quadratic equation.
