    h(t) = -16t^2 +16t + 32 = 0

    solve for t

    The 32 in the equation reflects that he is 32 feet above the water or.ground. The question says both. Is that a mistake?

    h(t) = -16t^2 +16t + 32

    0 = -16t^2 +16t +32

    0 = -16(t^2 -t -2)

    0 = (t.-2))t +1)

    t.= -1 sec or 2 sec

    Reject negative time.

    t = 2 seconds

    2 seconds or of course -1 seconds if that makes sense
