Vector A has magnitude of 13.9 and is 225° counter-clockwise up from the x-axis. What are the x- and y-components of the vector?

Solution

The x- and y-components of the vector are

$$A _ {x} = A \cos \theta = 13.9 \cos 225{}^{\circ} = -9.83,$$ $$A _ {y} = A \sin \theta = 13.9 \sin 225{}^{\circ} = -9.83.$$

Answer: -9.83, -9.83.
