A cyclist applies the brakes while travelling along a level road. The braking force has a magnitude of 180 N and acts over a distance of 12 m. The cyclist and bicycle come to rest.
Use E=F×dE = F \times dE=F×d to calculate the work done against friction.
Explain the changes in the energy stores of the cyclist, bicycle and surroundings as the brakes act.
