A ball is thrown vertically upward from the edge of a bridge 26.5 m high with an initial speed of 11.0 m/s. The ball falls all the way down and strikes the water below. Determine the magnitude of the velocity of the stone just before it strike the water. (In m/s)

  1. solve for t in

    26.5 + 11.0t - 4.9t^2 = 0

    Then use that value for t in

    v = 11.0 - 9.8
