A slender rod ACB of length 1.50 m and mass of 15.0 kg is pinned at point C, which is 0.30 m from end B. End B of the slender rod is pressed against a spring of constant k = 300000 N/m. At the position shown when the slender rod is horizontal, the spring is compressed by 25 mm. The spring is not attached to the slender rod. The rod is released from rest at the position shown and rotates counterclockwise by 90 degrees to a vertical position. Determine the (1) work done by the spring and the (2) work done by the weight of the slender rod.
