Problem
A toy car of mass 0.5 kg moves along a straight track at constant speed. The forward driving force on the car is 0.8 N and friction acts backward with a force of 0.8 N. State whether the net force on the car is zero or non-zero. Classify the overall force as balanced or unbalanced and justify your answer.
