A claw hammer is used to pull a nail out of a board (Fig. P11.52). The nail is at an angle of 60º to the board, and a force F₁of magnitude 400 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 F₂is applied to the hammer handle at a distance of 0.300 m above the board. What magnitude of force F₂is required to apply the required 400-N force (F₁) to the nail? (You can ignore the weight of the hammer.)
