Question
The system shown in the figure below, consisting of four particles connected by massless, rigid rods, is rotating around the x-axis with an angular speed of 2.60 rad/s. The particle masses are \( m_1 = 1.05 \, \text{kg}, \, m_2 = 4.05 \, \text{kg}, \, m_3 = 2.20 \, \text{kg}, \, \text{and} \, m_4 = 3.25 \, \text{kg}. \)

### Diagram Description

The diagram displays four particles aligned vertically with varying distances from the x-axis (horizontal line). Each particle has the following vertical positions (y-coordinates):

- \( m_1 \) at \( y = 2.00 \, \text{m} \)
- \( m_2 \) at \( y = 1.00 \, \text{m} \)
- \( m_3 \) at \( y = -2.00 \, \text{m} \)
- \( m_4 \) at \( y = -4.00 \, \text{m} \)

### Questions

(a) What is the rotational inertia of the system around the x-axis?
\[ \text{Rotational Inertia: } \, \underline{\hspace{2cm}} \, \text{kg} \cdot \text{m}^2 \]

(b) Using \( K_r = \frac{1}{2}I\omega^2 \), what is the total rotational kinetic energy of the system?
\[ \text{Total Rotational Kinetic Energy: } \, \underline{\hspace{2cm}} \, \text{J} \]

(c) What is the tangential speed of each of the four particles?
\[
\begin{align*}
v_{m_1} &= \underline{\hspace{2cm}} \, \text{m/s} \\
v_{m_2} &= \underline{\hspace{2cm}} \, \text{m/s} \\
v_{m_3} &= \underline{\hspace{2cm}} \, \text{m/s} \\
v_{m_4} &= \underline{\hspace{2cm}} \, \text{m/s} \\
