This question is about vehicle safety, stopping distances, and forces.
Explain how various factors affect the total stopping distance of a vehicle by separately considering thinking distance and braking distance.
Write down the equation that links distance, force, and work done.
The work done by the braking force to stop a car is 640 000 J640\,000\text{ J}640000 J. The average braking force applied is 32 000 N32\,000\text{ N}32000 N. Calculate the braking distance of the car.
Explain the potential safety dangers to the vehicle's motion when it undergoes an extremely large deceleration during emergency braking.
