Is it possible for a truck and a motorcycle to have the same momentum?

• Yes, if they have the same mass and velocity.

• Yes, if the product of their mass and velocity is equal.

• No, because a truck is always heavier than a motorcycle.

• No, because a motorcycle cannot reach the same speed as a truck.
