Question
When a small car pulls a trailer for a move, which of the following explains why the trailer moves? Select one: a·The car exerts a larger force on the trailer than the trailer does on the car. O b. The action-reaction pair is in the linkage, which pulls the trailer with larger force than that with which it pulls the car. c. While the force of the trailer on the car is equal and opposite to the force of the car on the trailer, the total of all forces acting on the car are unbalanced. d. The trailer will not move.Explanation / Answer
A car pulls a trailor for a move,the contact force between car and trailor are equal, which means force of trailor on car is equal and opposite to the force of the car on trailor. The total (pulling) of all forces acting on the car are unbalenced.Hence car pulls a trailor for a move.
Therefore, (C) is correct option.
