10.59 - Moment of Inertia and Rotational Kinetic Energy Points:30 An aircraft is coming in for a landing at 292 meters height when the propeller falls off. The aircraft is flying at 34.0 m/s horizontally. The propeller has a rotation rate of 19.0 rev/s, a moment of inertia of 74.0 kg-m², and a mass of 184 kg. Neglect air resistance. With what translational velocity does the propeller hit the ground? Tries 0/40 Submit Answer What is the rotation rate of the propeller at impact? (You do not need to enter any units.) rev/s Submit Answer Incorrect. Tries 1/40 Previous Tries If air resistance is present and reduces the propeller's rotational kinetic energy at impact by 28.0%, what is the propeller's rotation rate at impact? (You do not need to enter any units.) rev/s Submit Answer Tries 0/40
