To find the acceleration when the net force is 20.0 N and mass is 5.0 kg, we can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
Where:
- \( F \) is the net force (in Newtons),
- \( m \) is the mass (in kilograms), and
- \( a \) is the acceleration (in m/s²).
Given:
- Net force \( F = 20.0 \) N
- Mass \( m = 5.0 \) kg
We can rearrange the formula to solve for acceleration \( a \):
\[ a = \frac{F}{m} \]
Now, substituting the values:
\[ a = \frac{20.0 , \text{N}}{5.0 , \text{kg}} = 4.0 , \text{m/s}^2 \]
Thus, the value that would complete the last cell is 4.0.
