To determine the mass of the encyclopedia, we can use the formula derived from Newton's second law of motion:
\[ m = \frac{F}{a} \]
Where:
- \( m \) is the mass,
- \( F \) is the net force,
- \( a \) is the acceleration.
Given:
- \( F = 30 \, \text{N} \)
- \( a = 2 \, \text{m/s}^2 \)
Now plug the values into the formula:
\[ m = \frac{30 \, \text{N}}{2 \, \text{m/s}^2} \]
\[ m = 15 \, \text{kg} \]
Thus, the mass of the encyclopedia is **15 kg**.
The correct answer is **A. 15 kg**.
\[ m = \frac{F}{a} \]
Where:
- \( m \) is the mass,
- \( F \) is the net force,
- \( a \) is the acceleration.
Given:
- \( F = 30 \, \text{N} \)
- \( a = 2 \, \text{m/s}^2 \)
Now plug the values into the formula:
\[ m = \frac{30 \, \text{N}}{2 \, \text{m/s}^2} \]
\[ m = 15 \, \text{kg} \]
Thus, the mass of the encyclopedia is **15 kg**.
The correct answer is **A. 15 kg**.
