Question

How much force is needed to make a 60 kg object accelerate at a rate of 2.0 m/s2?

Answer 1

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.
