Question

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

Answer 1

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 = $\frac{980}{9.8}$   = 100kg
