The question you asked is a physics problem involving Newton's second law of motion, which states that force equals mass times acceleration (F = m * a). In this case, you are asking about the force needed to produce a certain acceleration for a given mass.
To solve the problem:
- Identify the mass (m): 15 kg
- Identify the acceleration (a): 3 m/s²
- Apply the formula (F = m * a): \[ F = 15 , \text{kg} \times 3 , \text{m/s}^2 = 45 , \text{N} \]
Therefore, the force needed to produce the specified acceleration is 45 Newtons (N).
As for how to categorize the question, it can be considered a straightforward scientific inquiry rather than a polite or bossy question.
