A wheel rotates about a fixed axis with an initial angular velocity of 20 rad/s. During a 5.0-s interval, the angular velocity decreases to 10 rad/s. Assume that the angular acceleration is constant during the 5.0-s interval. How many radians does the wheel turn through during the 5.0-s interval

The angular displacement of the wheel is 45 radians

Explanation:

Given;

initial angular velocity, ω₀ = 20 rad/s

final angular velocity, ωf = 10 rad/s

time interval, t = 5

Angular acceleration is calculated as;

|α| = 2 rad/s²

Angular displacement is calculated as;

Therefore, the angular displacement of the wheel is 45 radians
