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,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.
Given:
- Mass \( m = 60 \, \text{kg} \)
- Acceleration \( a = 2.0 \, \text{m/s}^2 \)
Now, plug in the values:
\[ F = 60 \, \text{kg} \cdot 2.0 \, \text{m/s}^2 \]
\[ F = 120 \, \text{N} \]
So, the required force is **120 N**.
\[ F = m \cdot a \]
where:
- \( F \) is the force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.
Given:
- Mass \( m = 60 \, \text{kg} \)
- Acceleration \( a = 2.0 \, \text{m/s}^2 \)
Now, plug in the values:
\[ F = 60 \, \text{kg} \cdot 2.0 \, \text{m/s}^2 \]
\[ F = 120 \, \text{N} \]
So, the required force is **120 N**.
