A boy pulls a wagon with a force of 6 N east as another boy pushes it with a force of 3 N east. What is the net force?

Options

A. 2 N
B. 18 N
C. 9 N
D. 3 N

Answer

To find the net force acting on the wagon, we need to consider the forces applied by both boys. Here's how we can solve the problem step by step:

### Step 1: Identify the Forces
- The first boy pulls the wagon with a force of **6 N** to the **east**.
- The second boy pushes the wagon with a force of **3 N** to the **east**.

### Step 2: Determine the Direction of the Forces
Both forces are acting in the same direction (east). This means we can simply add the magnitudes of the forces together.

### Step 3: Add the Forces
To find the net force, we add the two forces together:
- Net Force = Force from Boy 1 + Force from Boy 2
- Net Force = 6 N (east) + 3 N (east)

### Step 4: Calculate the Net Force
Now, we perform the addition:
- Net Force = 6 N + 3 N = **9 N** (east)

### Conclusion
The net force acting on the wagon is **9 N** to the **east**.
