What is the mass of a body to which a force of 40 N imparts an acceleration of 2 m / s2?


F = 40 Newton – force imparting acceleration to the body;

a = 2 m / s ^ 2 – body acceleration.

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

According to Newton’s second law:

F = m * a, hence:

m = F / a = 40/2 = 20 kilograms.

Answer: body weight is 20 kilograms.
