A motorcycle travels at a constant speed vvv on a horizontal, straight test track. The rider sees a signal to stop ahead.
Explain why the thinking distance is directly proportional to vvv.
When the brakes are applied, the motorcycle decelerates uniformly to rest. The frictional force applied by the brakes is constant. Explain why the braking distance is proportional to v2v^2v2.
The motorcycle is travelling at 24 m/s24\text{ m/s}24 m/s.
The thinking distance is 16 m16\text{ m}16 m. Calculate the time taken to travel the thinking distance.
