An old millstone, used for grinding grain in a gristmill, is a solid cylindrical wheel that can rotate about its central axle with negligible friction. The radius of the wheel is 0.330 m. A constant tangential force of 300 N applied to its edge causes the wheel to have an angular acceleration of 0.920 rad/s2. (a) What is the moment of inertia of the wheel (in kg - m2)? (b) What is the mass (in kg) of the wheel? ke (c) The wheel starts from rest and the tangential force remains constant over a time period of 4.50 s. What is the angular speed (in rad/s) of the wheel at the end of this time period? T Need Help? |[[Reagit] Submit
