You are on a cruise ship traveling north at a speed of 13.0 m/s with respect to land.

1) If you walk north toward the front of the ship, with a speed of 2.7 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 2.6 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 11.0 m/s. As you walk toward the back of your ship at 2.6 m/s, what is your velocity with respect to your friend?
