To calculate Joe's weight on Earth, you can use the formula:
\[
\text{Weight} = \text{mass} \times \text{gravity}
\]
where the acceleration due to gravity on Earth is approximately \(9.81 \, \text{m/s}^2\).
Given that Joe’s mass is \(68 \, \text{kg}\):
\[
\text{Weight} = 68 \, \text{kg} \times 9.81 \, \text{m/s}^2 \approx 667.08 \, \text{N}
\]
So, rounding this value gives us approximately 667 N.
Therefore, the correct answer is:
**A. 667 N**.
