Question

### Physics Problem: Force and Motion

1. **Calculate the initial speed of the son after the push.**
\[ \_\_\_\_ \, \text{m/s} \]

2. **Calculate the magnitude of the average force exerted on the son by the mother during the push.**
\[ \_\_\_\_ \, \text{N} \]

3. **The magnitude of the average force exerted on the mother by the son during the push is**
\[
\text{( ) less than} \\
\text{(•) equal to} \\
\text{( ) greater than}
\]

4. **The direction of the average force exerted on the mother by the son during the push is**
\[
\text{( ) the same as} \\
\text{(•) opposite to}
\]

5. **Problem Context:**
- After the initial push, the friction that the ice exerts cannot be considered negligible.
- The mother comes to rest after moving a distance of 9.8 m across the ice.
- If the coefficient of friction (\( \mu \)) is the same for the son, how far does the son move after the push?

### Explanation:

- **Newton's Third Law** states that for every action, there is an equal and opposite reaction. This principle is demonstrated in the questions about the forces exerted by the mother and son on each other.
- **Friction and Motion**: Once motion begins, friction acts as a retarding force, bringing the objects to rest. Calculating the stopping distance involves understanding and applying the concepts of friction and kinetic energy.

**Diagram Description:**

The image shows a line drawing of a woman and a child standing on an ice rink. They are facing each other with their hands raised as if they are pushing one another. Horizontal lines indicate the surface of the ice rink beneath their feet.

**Transcription:**

A 68.9 kg woman and her 31 kg son are standing at rest on an ice rink. They push against each other for a time of 0.73 s, causing them to glide apart. (Assume friction is negligible during the push.) The speed of the woman immediately after they separate is 4 m/s.
