9.38 An airplane propeller is 1.86 mm in length (from tip to tip) with mass 116 kgkg and is rotating at 2900 rpmrpm (rev/minrev/min) about an axis through its center. You can model the propeller as a slender rod. Part A What is its rotational kinetic energy? Part B 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 uniform stick 1.0 m long with a total mass of 300.0 g is pivoted at its center. A 3.0 g bullet is shot through the stick midway between the pivot and one end. The bullet approaches at 250 m/s and leaves at 160 m/s. With what angular speed is the stick spinning after the collision, if the bullet strikes the stick perpendicularly? (The moment of inertia of a uniform stick rotating about its center is I = (1/12)mL2.)
