What acceleration was acquired by a car with a mass of 1 ton with a movement

What acceleration was acquired by a car with a mass of 1 ton with a movement resistance force of 600 N, if an external force of 800 N acts on it?

m = 1 t = 1000 kg.

Fcopr = 600 N.

Fvn = 800 N.

a -?

According to 2 Newton’s law, the acceleration of a body is directly proportional to the resultant of all forces F that act on the body and inversely proportional to the mass of the body: a = F / m.

The resultant of all forces F, is the vector sum of all forces that act on the body: F = Fвн + Fсopr.

The resistance force Fsopr directed in the opposite direction of the body movement, and therefore in the opposite direction to the external force Fвн.

F = Fвн – Фср.

a = (Fvn – Fcopr) / m.

a = (800 N – 600 N) / 1000 kg = 0.2 m / s ^ 2.

Answer: the car has acquired acceleration a = 0.2 m / s ^ 2.
