Answer:

W'=125.44 N

Explanation:

The weight of a person on the surface of Earth is 784 N

Weight is given by :

W = mg

m is mass of the person and g is acceleration due to gravity on the surface of Earth (10 m/s²)

[tex]m=\dfrac{W}{g}\\\\m=\dfrac{784}{10}\\\\m=78.4\ kg[/tex]

The acceleration due to gravity on the surface of Moon, g' = 1.6 m/s²

Weight of the person on the moon is :

W'=mg'

[tex]W'=78.4\ kg\times 1.6\ m/s^2\\\\W'=125.44\ N[/tex]

Hence, the person would weigh 125.44 N on the Moon.

Answer:

129 N

Explanation:

The answer you're looking for is 129 N

Weight on Earth, divide by Earth's gravity (≈9.80), multiplied by the gravity of the Moon (≈1.60).
