An old grindstone, used for sharpening tools, 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 3-30 N applied to its edge causes the wheel to have an angular acceleration of 0.864 radfs2. (a) What is the moment of inertia of the wheel (in kg - m2]? :I kg - m2 (b) What is the mass (in kg) of the wheel? |:|k9 (c) The wheel starts from rest and the tangential force remains constant over a time period of 4.00 5. What is the angular speed (in radfs) of the wheel at the end of this time period? |:| rams
