The diagram above shows a load that will be lifted using a lever. The distance from the tip of the fulcrum to the end of the board carrying the load is 5 m. The entire length of the board is 15 m. The end of the board where force will be applied is 3 m off the ground. How much work will be done if the load is raised as high as the lever can raise it, and the force used is 500 N? A. 497 N·m B. 1,500 N·m C. 167 N·m D. 3 N·m
