The effects of inertia and velocity illustrate why a high performance car needs a brake system with greater stopping power than an economy car with only modest performance.

Question

Quizplus · Accepted Answer

This statement is true because a high performance car is capable of reaching higher speeds and has more mass which increases its inertia. A brake system with greater stopping power is necessary to counteract this momentum and bring the car to a safe and controlled stop. An economy car with modest performance has a lower maximum speed and less mass, therefore its brake system does not need to be as powerful.
