Question

A light rope is wrapped around a frictionless pulley. On one end is attached a 4 kg mass, and on the other end a 60 N force is applied downward: A. Calculate the acceleration of the 4 kg mass. (5.2 m/s² up) B. Suppose a 3 kg mass is connected to the free end of the rope. Calculate the acceleration of the 4 kg mass now. (Assume the 60 N is no longer applied).

Light rope is wrapped around a frictionless pulley. On one end, a force of 60 N is applied downward. A kg mass is connected to the free end of the rope. Calculate the acceleration of the kg mass (5.2 m/s^2 up). Suppose the kg mass is connected to the free end of the rope. Calculate the acceleration of the kg mass now. (Assume the 60 N force is no longer applied)
