Final answer:
The weight of a person with a mass of 66.7 kg on Earth is 654 N after rounding to the nearest whole number, making Option 2: 654 N the correct answer.
Step-by-step explanation:
To determine the weight of a person on Earth, you can use the formula w = mg, where w stands for weight, m is the mass, and g is the acceleration due to gravity. On Earth, g is approximately 9.80 m/s². For a person with a mass of 66.7 kg, their weight on Earth would be calculated as:
w = (66.7 kg)(9.80 m/s²) = 653.46 N.
Since we need to report the answer in whole numbers, we can round it to the nearest newton, resulting in 654 N. Therefore, the closest option is Option 2: 654 N.
