What is the approximate mass of a body weighing 120 N (newton)?

Given:

G = 120 Newton – body weight;

It is required to determine m (kilogram) – what is the approximate mass of the body.

We believe that no other forces and accelerations act on the body (that is, the body is at rest or moves uniformly and rectilinearly. Then, in order to determine the mass, it is necessary to apply the following formula:

G = M * g (where g = 9.8 N / kg (Newton per kilogram)), from here we find that:

M = G / g = 120 / 9.8 = 1200/98 = 12.2 kilograms (rounded to one decimal place).

Answer: The body has an approximate mass of 12.2 kilograms.
