Question

During one scene in the movie, X-Men: Days of Future Past, Magneto uses his magnetic powers to drag Mystique across the ground toward him, relying on a bullet that has been lodged in Mystique’s calf to pull her with a magnetic force, as shown below. Assume that Mystique has a mass of 63.8 kg and that the coefficient of kinetic friction between her and the ground is 0.321. With what force should Magneto pull her if the direction of his magnetic force is 30 degrees above the horizontal, and he wants to pull her toward him at a constant speed of 2 m/s? Give your answer in Newtons.
