### Current Attempt in Progress

A ceiling fan is turned on and a net torque of 2.9 N·m is applied to the blades. The blades have a total moment of inertia of 0.23 kg·m². What is the angular acceleration of the blades?

---

**Answer:**

To calculate the angular acceleration (\(\alpha\)) of the blades, use the formula:

\[ \tau = I \cdot \alpha \]

Where:
- \(\tau\) is the net torque
- \(I\) is the moment of inertia
- \(\alpha\) is the angular acceleration

Given:
- \(\tau = 2.9 \, \text{N·m}\)
- \(I = 0.23 \, \text{kg·m}^2\)

Rearrange the formula to solve for the angular acceleration:

\[ \alpha = \frac{\tau}{I} \]

Substitute the given values:

\[ \alpha = \frac{2.9 \, \text{N·m}}{0.23 \, \text{kg·m}^2} \]

\[ \alpha = 12.61 \, \text{rad/s}^2 \]

Thus, the angular acceleration of the blades is \(12.61 \, \text{rad/s}^2\). 

To enter this solution in the given fields:
- Number: `12.61`
- Units: `rad/s²`
