Answer :
Final answer:
The weight of an object with a mass of 250 kg under Earth's gravity (9.8 m/s²) would be 2450 kg*m/s², therefore, the correct answer is option B.
Explanation:
The weight of an object is calculated by multiplying its mass by the acceleration due to gravity. In this case, the object's mass is 250 kg and the Earth's gravity is 9.8 m/s². So, the weight of the object would be: 250 kg * 9.8 m/s² = 2450 kg*m/s², which is also referred to as Newtons (N).
Therefore, the correct answer is option B) 2450 kg*m/s².
