Question
Consider the pulley and mass system below. The center of mass of the pulley is fixed. Assume the mass accelerates downward when the system is released from rest. What is the direction of the torque caused by the tension in the cord?Group of answer choicesTo the leftUpwardOut of the pageInto the pageDownwardTo the rightNone of these
Solution
The direction of the torque caused by the tension in the cord can be determined by considering the motion of the system. Since the mass accelerates downward when the system is released from rest, we can conclude that the torque caused by the tension in the cord is directed downward.

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of ½ MR2. If m1 is 4.00 kg, m2 is 4.00 kg, and M is 4.00 kg, then what is the tension in the string attached to m2?
