A cyclist rides a bicycle in a straight line on a horizontal road. The cyclist produces a forward driving force of 180 N.
The frictional force between the bicycle tyres and the road is 40 N, and the air resistance acting on the cyclist and bicycle is 110 N.
What is the resultant force acting on the cyclist and bicycle?
