To find the force needed to accelerate an object, you can use Newton's second law of motion, which states:
\[ F = ma \]
where:
- \( F \) is the force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.
Given:
- Mass (\( m \)) = 5 kg,
- Acceleration (\( a \)) = 6 m/s².
Now, plug in the values:
\[ F = 5 \, \text{kg} \times 6 \, \text{m/s}^2 \]
\[ F = 30 \, \text{N} \]
Therefore, the force needed is **30 N**.
\[ F = ma \]
where:
- \( F \) is the force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.

- Acceleration (\( a \)) = 6 m/s².
Now, plug in the values:
\[ F = 5 \, \text{kg} \times 6 \, \text{m/s}^2 \]
\[ F = 30 \, \text{N} \]
Therefore, the force needed is **30 N**.
