Question

A body of mass 40 Kg.What is his weight in Newton on the surface of the moon (Take g =9.8 ms-2 on earth and g=1.568ms-2 on moon)​

Answer 1

Weight = m * g.

Here, m = 40kg, g = 1.568 $m/s^2$, so:

Weight = 40 * 1.568 $kg-m/s^2$ = 62.72 Newtons.

Answer 2

Using the formula

W=mg

W= 40Kg × 1.568m/s²                     For moon  g=1.568m/s²  

W= 62.75kgm/s²

W=62.75N
