Diving board. In the figure below, a uniform diving board with mass m = 40 kg is 3.5 m long and is attached to two supports. When a diver stands on the end of the board, the support on the other end exerts a downward force of 1200 N on the board. At what distance from the left side of the board should the diver stand to reduce that force to zero? (Hint: First find the diver's mass.) 2.5 m 1.0 m Number Units m
