Angular Velocity from Time-Varying Torque
A wheel with a moment of inertia of 2 kg·m² is initially rotating with an angular velocity of 5 rad/s. For the time interval 0 ≤ t ≤ 4 s, the wheel is subjected to a time-varying torque given by the function τ(t) = (2 - t) N·m. What is the angular velocity of the wheel at t = 4 s?
A
7 rad/s
B
5 rad/s
C
1 rad/s
D
3 rad/s
