Question

### Topic: Moments and Centroid of a Lamina

#### Problem Statement:
Find \( M_x \), \( M_y \), and \( (\bar{x}, \bar{y}) \) for the lamina of uniform density \( \rho \) bounded by the graphs of the equations.

\[ y = x^{2/3}, \quad y = \frac{1}{2} x \]

#### Solution Strategy:

1. **Determine the Bounds of the Region:**
- Identify the points where the graphs \( y = x^{2/3} \) and \( y = \frac{1}{2} x \) intersect.
- Set \( x^{2/3} = \frac{1}{2} x \) and solve for \( x \).

2. **Compute the Moments \( M_x \) and \( M_y \):**
- Use the formulas for the moments of a lamina.
- Set up the integrals to calculate \( M_x \) and \( M_y \).

3. **Find the Coordinates of the Centroid \( (\bar{x}, \bar{y}) \):**
- Use the moments found in the previous step to compute \( \bar{x} \) and \( \bar{y} \).

#### Calculation Details:

- **Defining Moments:**
- \(M_x = \int_a^b \int_{g_1(x)}^{g_2(x)} y \rho \, dy \, dx \)
- \(M_y = \int_a^b \int_{g_1(x)}^{g_2(x)} \rho x \, dy \, dx \)

- **Centroid Coordinates:**
- \( \bar{x} = \frac{M_y}{M} \)
- \( \bar{y} = \frac{M_x}{M} \)

#### Result:

\[ M_x = \boxed{\text{Integral Result and Explanation}} \]
\[ M_y = \boxed{\text{Integral Result and Explanation}} \]
\[ (\bar{x}, \bar{y}) = \left( \boxed{\text{Calculated } \bar{x}}, \boxed{\text{Calculated } \bar{y}} \right) \]

### Explanation of Graphs and Diagrams:

- **Equations Graphs:**
- \( y = x^{2/3} \): A curve that
