A boy is running to the east and jumps into a stationary boat in a lake. Once the boy lands in the boat, the boat moves to the east. Which best compares the initial momentum of the boy with the final momentum of the boy/boat system?

The initial momentum of the boy is zero because the velocity cancels with the mass of the boy.
The initial momentum of the boy is greater than the boy/boat because the boy has a greater velocity than the boat.
The initial momentum of the boy is less than the boy/boat because the boy has less mass than the boat.
The initial momentum of the boy is equal to the boy/boat because the final velocity of the boat is less than the initial velocity of the boy.
