Explain step by step

(10%) Problem 4: A water wheel with radius Ry = 1.8 m and mass My = 1.95 x 10' kg is used to power a grain mill next to a river Treat the water wheel as a hollow cylinder. The rushing water of the river rotates the wheel with a constant frequency f, = 2.2 Hz. Randomized Variables Roy = 1.8 m My = 1.95 x 10' kg fr = 2.2 Hz Ilekendi michael, Sharon - soileken @cengarnetrih edu @theexpertta. com- fracking id: 5188-E5-24-48-BDF3-48835.
