An airplane propeller is 2.00 m in length (from tip to tip) with mass 99.0 kg and is rotating at 2900 rpm (rev/min) about an axis through its center. You can model the propeller as a slender rod. What is its rotational kinetic energy? 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...

A uniform, 0.0350 kg rod of length 0.450 m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.0200 kg, are mounted so that they can slide without friction along the rod. They are initially held by catches at positions 0.0550 m on each side of the center of the rod, and the system is rotating at 48.0 rev/min. With no other changes in the system,...

1. Starting from rest, a CD takes 3.0 s to reach its operating angular velocity of 450 rpm. The mass of a CD is 17 g and its diameter is 12 cm. You may assume that the small opening at the center of the CD is unimportant when calculating the rotational inertia. Assume that the angular acceleration is constant. a. What is the rotational kinetic energy of the CD after it has completely spun up? b. How high off the...
