To find the force needed to accelerate an object, you can use Newton's second law of motion, which is defined as:
\[ F = m \cdot a \]
where \( F \) is the force in newtons (N), \( m \) is the mass in kilograms (kg), and \( a \) is the acceleration in meters per second squared (m/s²).
Given:
- Mass \( m = 60 \) kg
- Acceleration \( a = 2.0 \) m/s²
Now, plug the values into the formula:
\[ F = 60\, \text{kg} \cdot 2.0\, \text{m/s²} \]
\[ F = 120\, \text{N} \]
So, the correct answer is **120 N**.
\[ F = m \cdot a \]
