## Homework Statement

A model for the suspension of a vehicle is shown where the spring has stiffness k = 178 N.mm and an unstretched length of 347 mm.

**Here is the picture: http://i.imgur.com/1dTVs12.jpg**

Part a asked to determine the value of P and the force supported by member AB so that the suspension was in equilibrium, and I got that right.

However part b asks

**"If P = 0, determine the x and y coordinates of point A, namely x**

_{A}and y_{A}."## Homework Equations

Law of sines

Law of cosines

Basic trig

## The Attempt at a Solution

I used the law of cosines to find all the angles

A = 15.737 degrees

B = 138.128 degrees

C = 26.135 degrees

I don't know where to go from here to find the coordinates, I feel like this is probably really easy but I'm over thinking it.

Thank you so much for your help!
