A car traveling along the highway brakes to a stop. A greater braking force is required when the car has:
Understand the Problem
The question is asking which condition requires a greater braking force for a car to stop. The options suggest different factors such as stopping distance, mass, and momentum that influence braking force.
Answer
All of the above.
The final answer is all of the above.
Answer for screen readers
The final answer is all of the above.
More Information
More braking force is needed with less stopping distance, more mass, or more momentum. All these factors either increase the required deceleration or the inertia that needs to be overcome.
Tips
A common mistake is to consider only one factor. Remember that mass, velocity, and stopping distance all influence the braking force required.
