Final answer:
To find the mass of an object, divide the force (2700 N) by the acceleration (15 m/s²), resulting in a mass of 180 kg.
Step-by-step explanation:
To find the mass of an object with a force of 2700 N and an acceleration of 15 m/s², we use Newton's second law of motion: Force (F) = Mass (m) × Acceleration (a). To find the mass, we rearrange the formula to get: m = F / a.
Plugging in the given values:
- Force (F) = 2700 N,
- Acceleration (a) = 15 m/s².
The mass (m) can be calculated as follows:
m = 2700 N / 15 m/s² = 180 kg.
Therefore, the correct answer is b. 180 kg.
