A)
A. truck

cross out

B)
B. car

Answer 1

The correct answer is:

A. truck

Inertia is the property of an object to resist changes in its state of motion. It is directly related to mass. Since trucks generally have more mass than cars, they have more inertia. Therefore, the truck would require more force to slow down than the car when both are traveling at the same speed.
