A man pushed a box up a 20° ramp with 3.00 m with 75.0 N of force. How much work did the man do?

Newton's law of universal gravitation states that the force f between two masses, m1 and m2, is given below, where g is a constant and d is the distance between the masses. find an equation that gives an instantaneous rate of change of f with respect to d. (assume m1 and m2 represent moving points.)
