A small car and big truck are driving down
a two-lane highway on a rainy day. The car is in the left lane, and the truck is in the right lane.
Both vehicles are traveling North at the same speed (70 MPH). Both drivers see a traffic jam up
ahead, and they both slam on theirs brakes with all of their might at the same moment. The car comes
to a halt after traveling 30 feet. The truck, however, does not halt until 120 feet.

it take the truck longer to come to a complete stop even though both vehicles were moving at the same
speed?

quantities and scalar quantities are not the same thing | c. | The mass of the car
is much greater than the mass of the truck. | d. | The mass of the truck is much greater than the
mass of the car. |
