Energy, Force and Motion

Two trucks with different masses travel at the same speed down a hill toward a red light. What will happen when both trucks apply their brakes at the same time?

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

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