Transcribed Image Text:A 4.50-kg wheel that is 34.5 cm in diameter rotates through an angle of 13.8 rad as it slows down uniformly from 22.0 rad/s to 13.5 rad/s. What is the magnitude of the angular acceleration of the wheel?
22.5 rad/s²
O 111 rad/s²
O 0.616 rad/s²
O 10.9 rad/s²
O 5.45 rad/s²
Expert Solution
Step 1
Given data:
Initial angular velocity (ω0) = 22.0 rad/s
Final angular velocity (ω) = 13.5 rad/s
Angular displacement (Δθ) = 13.8 rad
Required:
The magnitude of the angular acceleration (α)
