I think A is correct. Following the answer from b, if the swan travels south as in part b, what will be its displacement after 8.5 hours?

Physics 20: Mrs. Tyler Assignment 3 Wu= velocity wind 6. Use the following information to answer parts a-c. Show all necessary work. A swan is flying at a speed of 17.5 m/s. There is a wind blowing Vow : velocity swan from the East at 12.5 m/s. Vow = - 17 . 5m/s ( east ) Visa - velocity swan vi/ growas if the swan pointed due South, what would be the magnitude and direction of its Vw = - 12. Sm/s velocity relative to the ground.
