Final answer:
The total stopping distance for a vehicle with air brakes is longer than that for a vehicle with hydraulic brakes due to increased distance traveled by the vehicle before coming to a complete stop.
Step-by-step explanation:
The total stopping distance for a vehicle with air brakes is longer than that for a vehicle with hydraulic brakes due to increased distance traveled by the vehicle before coming to a complete stop. When a driver applies the brakes in a vehicle with air brakes, it takes longer for the air pressure to build up and for the brake pads to make contact with the rotor, resulting in a longer stopping distance. On the other hand, in a vehicle with hydraulic brakes, the brake fluid immediately transfers the pressure to the brake pads, allowing for a faster response time and shorter stopping distance.
