Answer:
100kg
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 = [tex]\frac{980}{9.8}[/tex] = 100kg
