The front wheel of a car is turned in a clockwise direction by the engine as the car accelerates towards the right, as shown in the diagram. There is a force of friction between the wheel and the road. What are the directions of the frictional forces on the wheel of the car and on the road?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Adirection of frictional force on wheel: to the left, direction of frictional force on road: to the left
Bdirection of frictional force on wheel: to the left, direction of frictional force on road: to the right
Cdirection of frictional force on wheel: to the right, direction of frictional force on road: to the left
Ddirection of frictional force on wheel: to the right, direction of frictional force on road: to the right
✓ Correct answer
C: direction of frictional force on wheel: to the right, direction of frictional force on road: to the left
