Answer and see the solution →A cyclist is riding along a straight, level road. The diagram shows the horizontal forces acting on the cyclist and bicycle:
Diagram showing two forces acting horizontally on a bicycle (left: forward force from cyclist, right: friction from road) (a)[2 marks]Calculate the resultant force acting on the cyclist and bicycle.
(b)[2 marks]State what happens to the motion of the cyclist as a result of this resultant force.

Question 195
2 marks · Normal
Answer and see the solution →Explain why friction is sometimes useful and sometimes a problem in everyday life. Refer to one example of each.
Question 196
2 marks · Normal
Answer and see the solution →State two effects a force can have on an object.
Question 197
4 marks · Normal
Answer and see the solution →A satellite in space is affected by two main forces: the gravitational force of attraction from the Earth, and a small force from the solar wind acting in the opposite direction.
(a)[1 mark]Name the type of force that pulls the satellite towards the Earth.
(b)[2 marks]Explain the nature of gravitational force.
(c)[1 mark]If the force from the solar wind is 0.5 N and the force due to gravity is 100 N, calculate the resultant force on the satellite (assume both act along the same line but in opposite directions).
