Question

A man weighing 980 n on earth weighs only 163 n on the moon. his mass on the moon is kg

Answer 1

100kg

Step-by-step explanation:

His mass on the moon and the earth will be the same.

Weight = mass x acceleration due to gravity

Acceleration due to gravity = 9.8m/s²

Let us find the mass;

Weight on earth = 980N

Mass = ?

Insert the parameters and solve;

980 = mass x 9.8

mass =
`(980)/(9.8)` = 100kg
