Calculate what is the moment of inertia of the pulley

Reference no: EM13545983

A string is wrapped around a pulley with a radius of 2.0cm. The pulley is initally at rest. A constant force of 50N is applied to the string, causing the pulley to rotate and the string to unwind. The string unwinds 1.2m in 4.9 seconds. Find the angular acceleration at which the string unwinds. What is the moment of inertia of the pulley.
