An object is launched from the ground. The object's height, in feet, can be described by the quadratic function h (t) = 80t - 16t2, where t is the time, in seconds, since the object was launched. When will the object hit the ground after it is launched? Explain how you found your answer.

    Set h (t), time = 0.

    0 = 80t-16t^2

    -16t^2+80t = 0

    Factor

    -16t (t-5) = 0

    t = 0 (when launched)

    & t = 5
