An airplane propeller is 2.08 m in length (from tip to tip) and hasa mass of 117kg. The propeller is rotating at 2400 rev/minabout an axis through its' center.

a.) What is its rotational kinetic energy? Treat thepropeller as a slender rod

b.) If it were not rotating, how far would it have to drop infree fall to acquire the same kinetic energy?
