Determine what is its rotational kinetic energy

Reference no: EM13564801

An airplane propeller is 2.02 min length (from tip to tip) with mass 109 kg. The propeller is rotating at 2000 rev/min about an axis through its center.

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

__________ J

(b) If it were not rotating, how far would it have to drop in freefall to acquire the same kinetic energy?

__________ km
