A claw hammer is used to pull a nail out of a board (Fig. 11.38). The nail is at an angle of 60° to the board, and a force F, of magnitude 500 N applied to the nail is required to pull it from the board. The hammer head contacts the board at point A, which is 0.080 m from where the nail enters the board. A horizontal force F 2 is applied to the hammer handle at a distance of 0.300 m above the board. What magnitude of force F2 is required to apply the required 500-N force (F,) to the nail? (You can ignore the weight of the hammer.)
