If all vehicles are travelling at the same speed, which one would have the most kinetic energy?

• The motorcycle, because it can go much faster than the truck.

• The car, because it can carry 5 people.

• The truck, because it has more mass.

• If they are travelling at the same speed, they will have the same amount of kinetic energy.
