To find the force needed to accelerate an object, you can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
where:
- \( F \) is the force in newtons (N),
- \( m \) is the mass of the object in kilograms (kg),
- \( a \) is the acceleration in meters per second squared (m/s²).
Given:
- Mass \( m = 60 \) kg
- Acceleration \( a = 2.0 \) m/s²
Now, substitute the values into the equation:
\[ F = 60 \, \text{kg} \cdot 2.0 \, \text{m/s}^2 = 120 \, \text{N} \]
Therefore, the force needed is **120 N**.
\[ F = m \cdot a \]
where:
- \( F \) is the force in newtons (N),
- \( m \) is the mass of the object in kilograms (kg),
- \( a \) is the acceleration in meters per second squared (m/s²).
Given:
- Mass \( m = 60 \) kg
- Acceleration \( a = 2.0 \) m/s²
Now, substitute the values into the equation:
\[ F = 60 \, \text{kg} \cdot 2.0 \, \text{m/s}^2 = 120 \, \text{N} \]
Therefore, the force needed is **120 N**.
