  1. I guess it is high tide so the water reaches the cliff.
    Well, there is a constant horizontal speed, call it u=13 m/s
    so
    13 t = 60 (that is a serious cliff !)
    t = 60/13 = 4.615 seconds falling
    well
    h = Hi + Vi t - 4.9 t^2
    Hi is what we want
    Vi is initial vertical speed up = 0
    4.9 = g/2
    h = 0, bleak ocean height
    0 = Hi + 0 - 4.9 t^2
    Hi = 104 meters, yikes
