**Question 27: What net force acts on the wagon?**
To find the net force acting on the wagon, we can use Newton's second law, which states \( F = m \cdot a \).
Given:
- Mass (m) = 30.0 kg
- Acceleration (a) = 0.5 m/s²
Calculating the force:
\[
F = m \cdot a = 30.0 \, \text{kg} \cdot 0.5 \, \text{m/s}^2 = 15 \, \text{N}
\]
Therefore, the net force acting on the wagon is **15 N** (option c).

**Question 28: According to Newton’s second law, when the same force is applied to two objects of different masses...**
The correct answer is:
**b**: the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.
This is because, according to Newton’s second law (\( F = m \cdot a \)), when the same force is applied to two objects with different masses, the acceleration of each object is inversely proportional to its mass. The larger mass will have a smaller acceleration, and the smaller mass will have a larger acceleration.
