    Answer:

    7l07 sec

    Step-by-step explanation:

    The pertinent equation is s(t) = -16t^2.  We set this equal to zero to denote hammer hitting ground:  -16t^2 = -50 ft.  Solve for t^2 by dividing both sides by -16, obtaining

    t^2 = 50 ft^2

    The time required for the hammer to reach the ground is Sqrt(50 ft^2),

    or 7.07 sec
