**Understanding Moments of Inertia: Calculating for an Array of Point Objects**

This educational module covers the concept of calculating moments of inertia for a given array of point objects.

### Constants
- **\( m \):** 2.2 kg
- **\( M \):** 3.5 kg

### Problem Statement
Calculate the moment of inertia of the array of point objects shown in Figure 1:

1. **Part A**: About the vertical axis
2. **Part B**: About the horizontal axis

Both calculations require that the objects are connected by very light, rigid pieces of wire. The array is rectangular and the axes cut through the middle.

#### Figure Description
- The figure is labeled as "Figure 1 of 1".
- It shows a rectangle with dimensions:
  - **Horizontal sides:** 0.50 m and 1.50 m
  - **Vertical side:** 0.50 m

- The object placements are:
  - Masses \( M \) (3.5 kg) are at the bottom corners of the rectangle.
  - Masses \( m \) (2.2 kg) are at the top corners of the rectangle.
- A horizontal line labeled "Axis" is drawn through the center of the rectangle.

### Instructions
- **Express your answer using two significant figures.**
- Tools are provided for input in a field labeled \( I_y \) for the vertical axis and \( I_x \) for the horizontal axis.

### Submission
- There is a feedback system in place indicating four attempts are remaining for submission.

#### Graphical Interface
- The input fields next to the questions allow submission of answers.
- The figure helps visualize the problem and is essential for understanding the geometric layout of the problem.

This exercise illustrates how distribution and geometry affect moments of inertia in physical objects.

**Problem Statement:**

Calculate the moment of inertia of the array of point objects shown in the figure about the horizontal axis. Assume \( m = 2.2 \, \text{kg} \), \( M = 3.5 \, \text{kg} \), and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the horizontal axis. 

Express your answer using two significant figures.

\( I_x = \) [Input box] kg \(\cdot \) m\(^2\)

**Figure Explanation:**

The figure displays a rectangular array of point masses. The dimensions and placement are as follows:

- The horizontal line (parallel to the x-axis) is the axis of rotation.
- There are four point masses:
  - Two smaller point masses, \( m \), located at the top left and top right of the rectangle.
  - Two larger point masses, \( M \), located at the bottom left and bottom right of the rectangle.
- The distance between the top and bottom horizontal lines is 0.50 m.
- The distance between the left and right vertical lines is 1.50 m.
- The vertical distance from the horizontal axis to either of the horizontal lines is 0.50 m, essentially splitting the vertical length into two equal sections of 0.50 m each.

**Part C:**

About which axis would it be harder to accelerate this array?

- [ ] \( y \)
- [ ] \( x \)
