Let positive x-axis be East and positive y-axis be North.

**A.**

Vector A is north of west.

θ = 180° - 30° = 150°

1. Find out the x-component and y-component of the following vectors:

A = 15.0 cm; the vector is 30.00° north of west;

B = 12.0 m; the vector is 55.00° north of east;

C = 28.0 m/s; the vector is 40.00° south of west;

D = 55.5 m/s^{2}; the vector is 35.00° south of east.
