Amass m1 = 3.5 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 4.8 kg which hangs freely from the string. when released, the hanging mass falls a distance d = 0.71 m. 1) how much work is done by gravity on the two block system? 34 j (all of my answers are correct up to the last question, which i need on) 2) 2) how much work is done by the normal force on m1? 0 j 3) what is the final speed of the two blocks? 2.84 m/s 4) how much work is done by tension on m1? 14.1 j 5) what is the tension in the string as the block falls? 19.9 n 7) what is the net work done on m2? this is the question i need on. i gave the answers to the previous questions because something in there might be needed for solving this part of the problem.

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.)

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
