Chapter 9.7, Problem 9.8QQ
A cruise ship is moving at constant speed through the water. The vacationers on the ship are eager to arrive at their next destination. They decide to try to speed up the cruise ship by gathering at the bow (the front) and running together toward the stem (the back) of the ship. (i) While they are running toward the stern, is the speed of the ship (a) higher than it was before, (b) unchanged, (c) lower than it was before, or (d) impossible to determine? (ii) The vacationers stop running when they reach the stem of the ship. After they have all stopped running, is the speed of the ship (a) higher titan it was before they started running, (b) unchanged from what it was before they started running, (c) lower than it was before they started running, or (d) impossible to determine?
