How to Calculate Vector Components in Different Coordinate Systems?

[gbedenba]

Homework Statement

Let A= (3.5 m, vertically downward) and B = (4.1 m, 120° clockwise from ). Find the x and y components of and in each of the two coordinate systems shown in Figure Ex3.21. (attached)

Homework Equations

The Attempt at a Solution

I already have 0 for the x component of A for system 1 and -3.5 for the y component of of A for system one...I can't figure out the B x and y for system 1 . I can't find the A x&y and B x&y for system 2 help!

You'll need to use trigonometry (sin and cos) to find the x and y components of the vectors.
