You are on a cruise ship traveling north at a speed of 13 m/s with respect to land.
1) If you walk north toward the front of the ship, with a speed of 2.8 with respect to the ship, what is your velocity with respect to the land?
2) If you walk south toward the back of the ship, with a speed of 2.7 with respect to the ship, what is your velocity with respect to the land?
3) Your friend is sitting on another cruise ship traveling south at 12 m/s. As you walk toward the back of your ship at 2.7 m/s, what is your velocity with respect to your friend?
