Find the mass of the body if its weight is 9h.

Given:

P = 9 * h – body weight;

g = 9.8 m / s ^ 2 – acceleration of gravity.

It is required to determine the body weight m (kilogram).

Since it is not specified in the problem statement, we assume that the body rests on a horizontal support. Then, the weight of the body will be numerically equal to the force of gravity acting on this body, that is:

P = m * g, hence:

m = P / g = 9 * h / 9.8 = 0.9 * h kilogram.

Answer: body weight will be equal to 0.9 * h kilogram.
