The same unbalanced force acting on a 2.0-kilogram object will accelerate this object toward the north at 6.0 m/s².
What is Newton's Second Law?
According to Newton's second law, an object's acceleration is determined by its mass and the net force that is acting on it. The body's acceleration is inversely related to its mass and directly proportional to the net force applied on it
According to Newton's second Law of motion the resultant force is directly proportional to the rate of change in momentum.
Therefore; F = ma , where F is the force, m is the mass and a is the acceleration
F = 4 × 3
= 12 Newtons
The same force acts on a 2.0 kg object
F = ma
a = F/ m
= 12 /2
= 6.0 m/s²
