Question 2

Which has greater momentum in this photo: the non-moving ship or the kayak moving at the slow speed of 1 meter in ten seconds?
 a. The ship because of its overwhelmingly greater mass.
  b. The kayak because it has non-zero momentum while the ship at rest must have zero momentum.
  c. The momentum of an object is a meaningless concept if an object is not moving, so there is no clear answer to this question.
  d. The two momenta cannot be compared, because they point in different directions.
  e. Their momenta are equal.
