This question is about vehicle safety, stopping distances, and resistive forces.
Explain how various factors affect the total stopping distance of a heavy commercial vehicle, by separately considering thinking distance and braking distance.
State the equation that relates work done, force, and distance.
During emergency braking, a fully loaded quarry truck must dissipate 1.8 × 107 J of energy to come to a halt. If the braking system exerts an average retarding force of 3.6 × 105 N, calculate the braking distance of the truck.
Explain the potential physical and safety hazards regarding the vehicle's motion and stability when it undergoes extremely rapid deceleration during emergency braking.
