How much would a 70k

Answer :

First we calculate the weight of the moon.

Mass of the man on moon, m = 70 kg

Acceleration due to gravity, g = 1.63m/s2
(on the moon)

We know that: W = m × g

So, W = 70 × 1.63

W = 114.1N

Mass on the Earth, m = 70 kg

Acceleration due to gravity, g = 9.8 m/sec2

Weight on Earth=70 × 9.8 m/sec= 686 N

Thus the man would weigh 114.1 newtons on the moon. Please note that the mass of a body is constant everywhere in the universe. So, the mass of this man would be the same on the earth as well as on the moon, that is, that mass will be 70kg on the earth as well as on the moon.
