How does carrying extra passengers and heavy cargo alter your vehicle's performance when you apply the brakes?
- AThe vehicle halts more quickly without needing any adjustment to tyre pressures.
- The vehicle requires more time and space to come to a complete halt.Cevap
- CThe driver's reaction time lengthens while mechanical deceleration remains unaffected.
- DThe stopping distance remains identical unless road surface grip is reduced in wet weather.
Cevap
The vehicle requires more time and space to come to a complete halt.
Carrying additional mass increases the vehicle's kinetic energy and momentum at any given speed. Because the brakes must dissipate more energy to slow the heavier vehicle down, deceleration is slower and overall stopping distance extends significantly.
