Question:
| Problem 7:A water wheel with radiusRw=1.9m and massMw=1.95x 103kg 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 frequencyfr=1.5Hz. Randomized VariablesRw=1.9m Mw=1.95x 103kg fr=1.5Hz |
Part (a)Calculate the angular velocity w of the water wheel in radians/sec.
Part (b)Calculate the kinetic energy Kw, in J, of the water wheel as it rotates.
