What force must be applied for a body with a mass of 200 g to move with an acceleration of 1.5 m / s squared (0.3 N)?


m = 200 grams is the mass of a certain body;

a = 1.5 meters per second squared – the acceleration with which the body should move.

It is required to determine F (Newton) – what force must be applied to the body in order for it to move with an acceleration equal to a.

Let’s convert the units of measurement of mass to the SI system:

m = 200 grams = 200 * 10-3 = 200/1000 = 0.2 kilograms.

Then, to determine the force, it is necessary to use the following formula (Newton’s second law):

F = m * a;

F = 0.2 * 1.5;

F = 0.3 Newton.

Answer: a force equal to 0.3 Newton must be applied to the body.
