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 200 n applied to its edge causes the wheel to have an angular acceleration of 0.924 rad/s (a) what is the moment of inertia of the wheel (in kg m2)? kg m2 (b) what is the mass (in kg) of the wheel? kg (c) the wheel starts from rest and the tangential force remains constant overa time period speed (in rad/s) of the wheel at the end of this time period? of 5.50 s. what is the angular rad/s
