The speed of an object and the direction in which it moves constitute a vector quantity known as the velocity. An ostrich is running at a speed of 19.5 m/s in a direction of 65° north of west.

(a) What is the magnitude of the ostrich's velocity component that is directed due north?
1 m/s

(b) What is the magnitude of the ostrich's velocity component that is directed due west?
2 m/s
