A cyclist rides along a level road at a constant speed of 6.0 m/s.
The total mass of the cyclist and bicycle is 75 kg.
Calculate the kinetic energy of the cyclist and bicycle.
The cyclist increases her speed to 12 m/s.
A student says:
'The kinetic energy of the cyclist and bicycle also doubles.'
Explain why the student is wrong.
Later, the cyclist stops pedalling on the level road. The cyclist and bicycle slow down and stop.
Describe the changes in the way energy is stored as the cyclist and bicycle slow down.
