13-41.A 150-mm-diameter shaft with a mass of 20 kg is rotating at 900 rpm. A pulley mounted on the shaft hasa mass moment of inertia of 0.15 kg - m2. If the shaft and the pulley coast to a stop due to a tangentialfrictional force of 8 lb at the outer radius of the shaft, determine the time required.
