What force must be applied to a body with a mass of 500g so that it moves with an acceleration of 12m / s ^ 2

Let us find the resultant of all forces acting on a given body according to Newton’s second law: m • a = F. To calculate the force that must be applied to a body with a mass of m = 500 g = 0.5 kg (all values must be converted to SI units), moving with an acceleration of 12 m / s ^ 2, substitute these values of physical quantities in the formula and make calculations: F = 0.5 kg • 12 m / s ^ 2 = 6 N.
Answer: the force that must be applied to a given body is 6 Newtons.
