Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?

• The car with the smaller mass will require less force to stop than the car with the larger mass.

• The car with the larger mass will maintain its velocity while traveling down the hill.

• The car with the smaller mass will take longer to stop than the car with the larger mass.

• The car with the larger mass will have less inertia than the car with the smaller mass.
