A tire initially spins with an angular velocity of 12 rad/s, as shown in the figure below. When a constant braking force is applied, the tire begins to slow its spinning rate, and comes to rest after completing 10 additional full spins. How long did it take the tire to come to rest after the brakes were applied? An airplane propeller begins at rest. When the pilot starts the engine, the propeller accelerates with angular acceleration 𝛼 over a time of t seconds. Two position are marked on the propeller’s blade. Observe that position Y is twice as far from the rotation axis as is position X.
