Problem
A 2.5kg block is pulled across a horizontal table (μk=0.25) by a light string that passes over a smooth pulley of radius 0.04m and supports a 2.0kg hanging mass on the other side. The pulley’s axle offers a constant opposing torque of 0.05Nm, but its rotational inertia is negligible. The system is released from rest.
(i) Determine the acceleration of the system.
(ii) Find the tension in each segment of the string (one on either side of the pulley).
