Answer 1

To calculate the force required to accelerate an object, you can use Newton's second law of motion, which states that:

\[ F = m \cdot a \]

where:
- \( F \) is the force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.

In this case:
- \( m = 12 \, \text{kg} \)
- \( a = 65 \, \text{m/s}^2 \)

Now, plug in the values:

\[ F = 12 \, \text{kg} \cdot 65 \, \text{m/s}^2 \]

\[ F = 780 \, \text{N} \]

So, the force required to accelerate the 12 kg object by 65 m/s² is **780 N**.
