The car has a larger mass requiring less force to stop. The car has a smaller mass requiring more force to stop. The truck has a smaller mass requiring less force to stop. The truck has a larger mass requiring more force to stop.
I gave my students this multiple choice question: A car and a truck are traveling at the same rate of speed. The vehicles approach a stop sign. Which statement best explains why the car stops in a shorter distance than the truck?

Only one answer is correct among these 4 choices:
- The car has a larger mass requiring less force to stop.
- The car has a smaller mass requiring more force to stop.
- The truck has a smaller mass requiring less force to stop.
- The truck has a larger mass requiring more force to stop.

Could you tell me which one is correct?

The truck has a larger mass requiring more force to stop.
