To determine the mass of the box and the acceleration when it is pushed with a force of 10 N, we can use Newton's second law of motion, which states:
\[
F = m \cdot a
\]
Where:
- \( F \) is the applied force (in Newtons),
- \( m \) is the mass of the object (in kilograms),
- \( a \) is the acceleration of the object (in meters per second squared).
1. **When the box is empty**:
Let's assume the mass of the empty box is \( m_{\text{box}} \) kg. If a force of 10 N is applied:
\[
10 = m_{\text{box}} \cdot a_{\text{empty}}
\]
From this equation, we can rearrange it to determine the acceleration of the empty box:
\[
a_{\text{empty}} = \frac{10}{m_{\text{box}}}
\]
So, the acceleration of the empty box depends on its mass.
2. **After textbooks are added**:
Let's say the total mass of the box with the textbooks is \( m_{\text{total}} = m_{\text{box}} + m_{\text{textbooks}} \). If you continue to push with the same force of 10 N, the equation becomes:
\[
10 = m_{\text{total}} \cdot a_{\text{full}}
\]
Rearranging gives:
\[
a_{\text{full}} = \frac{10}{m_{\text{total}}}
\]
### Summary
- The acceleration when the box is empty will be \( a_{\text{empty}} = \frac{10}{m_{\text{box}}} \).
- The acceleration when textbooks are added will be \( a_{\text{full}} = \frac{10}{m_{\text{total}}} \), where \( m_{\text{total}} = m_{\text{box}} + m_{\text{textbooks}} \).
Since you didn’t provide the specific values for the mass of the box or the textbooks, I can’t give you numerical values for the accelerations. If you provide those values, I can help you calculate them!

To provide specific answers for the mass of the box and its acceleration, we need actual numerical values. However, I can provide an example with hypothetical numbers for clarity. Let's assume:
- The mass of the empty box (\( m_{\text{box}} \)) is \( 5 \, \text{kg} \).
- The mass of the textbooks (\( m_{\text{textbooks}} \)) is \( 15 \, \text{kg} \).
### Step 1: Acceleration of the Empty Box
Using Newton's second law (\( F = m \cdot a \)), we first find the acceleration of the empty box:
\[
a_{\text{empty}} = \frac{F}{m_{\text{box}}} = \frac{10 \, \text{N}}{5 \, \text{kg}} = 2 \, \text{m/s}^2
\]
### Step 2: Total Mass with Textbooks
The total mass of the box with the textbooks is:
\[
m_{\text{total}} = m_{\text{box}} + m_{\text{textbooks}} = 5 \, \text{kg} + 15 \, \text{kg} = 20 \, \text{kg}
\]
### Step 3: Acceleration with Textbooks
Now, we find the acceleration of the box when it is full of textbooks:
\[
a_{\text{full}} = \frac{F}{m_{\text{total}}} = \frac{10 \, \text{N}}{20 \, \text{kg}} = 0.5 \, \text{m/s}^2
\]
### Summary of Results
- **Mass of the empty box**: \( 5 \, \text{kg} \) (hypothetical example)
- **Acceleration of the empty box**: \( 2 \, \text{m/s}^2 \)
- **Total mass with textbooks**: \( 20 \, \text{kg} \)
- **Acceleration of the box with textbooks**: \( 0.5 \, \text{m/s}^2 \)
If you have specific values for the mass of the box and the textbooks, please provide them, and I can calculate the corresponding accelerations accurately!

Thank you for providing that context! Based on your question and the answers you've indicated, it appears you're looking for a conceptual understanding of the effects of loading the box with textbooks while applying the same force.
Let's summarize the reasoning that corresponds with your answers:
1. **Force Applied**: When you push the box with 10 N of force, you are applying the same force regardless of whether the box is empty or full.
2. **Acceleration**:
- When the box is **empty**, it has a certain mass \( m_{\text{box}} \) and experiences an acceleration \( a = \frac{F}{m_{\text{box}}} \) based on that mass.
- When you add textbooks to the box, the total mass increases \( m_{\text{total}} = m_{\text{box}} + m_{\text{textbooks}} \). With the same applied force of 10 N, the new acceleration will be \( a = \frac{F}{m_{\text{total}}} \).
- Since \( m_{\text{total}} \) is greater than \( m_{\text{box}} \), the acceleration **decreases** when you load the box with textbooks.
3. **Friction**: Assuming the frictional forces are constant, they may affect the effective acceleration, but if you are only asking about the box's response to the force applied, then:
4. **Answers Recap**:
- **Acceleration (of the box)**: **Decreased** (due to increase in mass).
- **Force (on the box)**: Stays the same (it is still applying 10 N).
- **Friction (if considered constant)**: Might influence the net acceleration, leading to scenarios where it **stayed the same** in context to a previous situation where textbooks were not present.
Thus, the answers to your specific questions can accordingly interpreted as:
- The acceleration **decreased** due to the increase in mass from the textbooks.
- The force you are applying **stayed the same**, as you are still pushing with 10 N.
If you have specific scenarios in mind, let me know, and I can provide further clarification!
