Question: A flywheel has a moment of inertia I and is rotating with an angular velocity ω. If a torque τ is applied for time t, what is the final angular velocity?

Options:

1. ω + (τ/I)t
2. ω - (τ/I)t
3. ω + (I/τ)t
4. ω - (I/τ)t

Correct Answer: ω + (τ/I)t

Solution:

Using the equation ω_f = ω + αt, where α = τ/I, we get ω_f = ω + (τ/I)t.
