A water wheel with radius Rw = 1.1 m and mass Mw = 1.55 x 10^3 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 fr = 1.9 Hz.
Randomized Variables:
Rw = 1.1 m
Mw = 1.55 x 10^3 kg
fr = 1.9 Hz
(a) Calculate the angular velocity ωw of the water wheel in radians/sec.
(b) Calculate the kinetic energy Kw, in J, of the water wheel as it rotates.
