A 12kg box resting on a horizontal, frictionless surface is attached to a 5kg weight (hanging off the side of the table) by a thin, light wire that passes over a frictionless pulley. The pulley has a shape of a uniform solid disk of mass 2kg and a diameter of .5m. After the system is released, find the tension in the wire on both sides of the pulley
The answer gives different tensions in the wire on either side of the pulley. How is that possible?
F = ma, torque = I*angular_acceleration
The Attempt at a Solution
(a) Tension between 12kg box and pulley = 32.7N, Tension between pulley and 5kg weight is 35.4N.
