the great gray-green, greasy zambezi river flowa over victoria falls in south central africa. the falls are approximately 108 m high. if the river is flowing horizontally at 3.60 m/s just before going over the falls, what is the speed of the water when it hits the bottom? assume the water is in freefall as it drop.

    s = 1/2 at^2
    108 = 4.9 t^2
    t = 4.69 sec

    v = at
    = 9.8*4.69
    = 46 m/s

    Extra credit: how far from the cliff base does the water hit?
