Kinematics and torque


A student hangs blocks with different masses from the pulley of mass M and radius r and releases them from rest. The student measures the time of the fall t and the magnitude of the angular velocity ωf when the blocks reach a distance d below the axle. There is no friction between the axle and pulley.
Which of the following plots could show the student’s measurements as a function of the applied torque on the pulley?
