To find the weight of a person on the Moon, you can use the formula:
\[
\text{Weight} = \text{mass} \times g
\]
where:
- mass = 90 kg
- \( g_{moon} = 1.64 \, \text{m/s}^2 \)
Now, substituting the values into the formula:
\[
\text{Weight} = 90 \, \text{kg} \times 1.64 \, \text{m/s}^2 = 147.6 \, \text{N}
\]
So the correct answer is:
C. 147.6 N
\[
\text{Weight} = \text{mass} \times g
\]
where:
- mass = 90 kg
- \( g_{moon} = 1.64 \, \text{m/s}^2 \)
Now, substituting the values into the formula:
\[
\text{Weight} = 90 \, \text{kg} \times 1.64 \, \text{m/s}^2 = 147.6 \, \text{N}
\]
So the correct answer is:
C. 147.6 N
