Question

If a person weighs 1000 N on the surface of the Earth, how much will they weigh on the surface of the Moon? What “g” value should we use to calculate the weight using Fg = mg?

Answer 1

Hence the weight of the person on the moon is 162.4, and the value of g used is 1.624 m/s²

Step-by-step explanation:

from the question,

W = mg........................ Equation 1

Where W = weight of the man on Earth, m = mass of the man, g = acceleartion due to gravity of the man

make m the subject of the equation

m = W/g.............. Equation 2

Given: W = 1000 N,

Constant: g = 10 m/s²

Therefore,

m = 1000/10

m = 100 kg

Weight on the moon

W' = mg'

W' = 100(1.624)

W' = 162.4 N.

Hence the weight of tthe person on the moon is 162.4, and the value of g used is 1.624 m/s²
