A ventilation fan with a moment of inertia of 0.040 kg·m² has a net torque of 0.160 N·m applied to it.What angular acceleration does it experience? A)0.0064 rad/s² B)4.0 rad/s² C)0.25 rad/s² D)0.40 rad/s² E)0.20 rad/s²

Question

Quizplus · Accepted Answer

The angular acceleration can be found using the formula $\alpha = \frac{\tau}{I}$, where $\alpha$ is the angular acceleration, $\tau$ is the torque, and $I$ is the moment of inertia. Plugging in the given values, $\alpha = \frac{0.160\, \text{N}\cdot\text{m}}{0.040\, \text{kg}\cdot\text{m}^2} = 4.0\, \text{rad/s}^2$.
