An airplane propeller is 1.85 m in length (from tip to tip) with mass 109 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. (a) what would its angular speed have to be, in rpm? (b) what is its rotational kinetic energy? k = 1.53×10^6
