Let's choose the rightwards as the positive direction. Let's assume that the 6 N force directed rightward and the 3 N force directed leftward. Then, we can find the net force acting on the object:


Fnet=6 N3 N=3 N.F_{net}=6\ N-3\ N=3\ N.

Finally, from the Newton's Second Law of Motion we can find acceleration produced by the system:


a=Fm=3 N3 kg=1.0 ms2.a=\dfrac{F}{m}=\dfrac{3\ N}{3\ kg}=1.0\ \dfrac{m}{s^2}.
