Verified Answer :

B117 N because you multiply 72 Kg with 1.63 m/s^2 and Kgm/s^2 is considered to be newtons

Answer: The weight of a 72.0 kg astronaut on the Moon is 117.36 N.

Explanation:

Mass of the astronaut on the moon , m= 72 kg

Acceleration due to gravity on moon,g  = 1.63 \(m/s^2\)

According to Newton second law of motion: F = ma

This will changes to = Weight = mass × g

\(Weight=72 kg\times 1.63m/s^2=117.36 N\)

The weight of a 72.0 kg astronaut on the Moon is 117.36 N.
