To find the force needed to make an object accelerate, 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, and
- \( a \) is the acceleration.
Given:
- Mass \( m = 60 , \text{kg} \)
- Acceleration \( a = 2.0 , \text{m/s}^2 \)
Now, substituting the given values into the equation:
\[ F = 60 , \text{kg} \times 2.0 , \text{m/s}^2 \]
\[ F = 120 , \text{N} \]
Therefore, a force of 120 Newtons is needed to make the 60 kg object accelerate at a rate of 2.0 m/s².
