An airplane propeller is 2.18 m in length (from tip to tip) with mass 121 kg and is rotating at 3000 rpm (rev/min) about an axis through its center. You can model the propeller as a slender rod.
Suppose that, due to weight constraints, you had to reduce the propeller's mass to 75.0% of its original mass, but you still needed to keep the same size and kinetic energy. What would its angular speed have to be, in rpm?
