Help needed with physics problem

How do I solve the following problem?


Find x-component of  vector v = (3.5 m/s , 30 degrees ,clockwise from the positive y-axis).


Find y -component of vector v = (3.5 m/s , 30 degrees clockwise from the positive y -axis).


Find x-component of vector a = (1.3 m/s^2 , 30 degrees, above the negative x -axis).


Find y -component of vector a = (1.3 m/s^2 , 30 degrees, above the negative x -axis).


Find x -component of vector F = (40.0 N , 36.9 degrees, counterclockwise from the positive y -axis).


Find y -component of vector F = (40.0 N , 36.9 degrees counterclockwise from the positive y -axis).


I just really need to know how to do these. Any kind of help would be really appreciated.

Did you draw and label diagrams? Use basic trig functions.

Find reference angles. Use cosine for x-component and sine for y-component. X is negative if vector left of y-axis and y negative if below x-axis due to rotation.

1 & 2 reversed, and 5 & 6 reversed. 5 should have negative
