Two weights, each weighing m, are hung over a pulley. If an additional weight of 100 g is attached to one of the weights, it is lowered by 564 cm in the first 2.00 s. What is the mass m? What was the force of the rope before adding the new weight? What is the force of the rope after adding the new weight?
