Question

The weight of a man on the surface of Earth is 588 N. Find his mass, taking `g=9.8 m//s^(2)`. If the man were taking to Moon, his weight would be 98 N. What is his mass on Moon?

Answer 1

Here, `W_(e)=588 N,m=?, g_(e)=9.8m//s^(2)`
From `W_(e)=mg_(e),m=(W_(e))/(g_(e))=(588)/(9.8)=60kg`
Again, `W_(m)=98 N,g_(m)=?`
Mass on Moon=mass on Earth = 60kg
`g_(m)=w_(m)/m=98/60=1.63m//s^(2)`
