The lorry exerts a force N on the trailer and the trailer exerts an equal but opposite force M on the lorry. The frictional force between the trailer and the road is F. Explain how the forces N, M and F enable the trailer to move

  

Answers


John
Resultant force between N and F causes motion. Since N is greater than F it overcomes frictional force F thereby enabling the trailer to move. N does not act on the trailer.
