Yes the mistake was in the moving of the left hand side...
Here is the proper way:
a2-g2x2+(µ(gx)2+2(a(µ(gx)))= 0
Now can I substitute in the variables or do I have to do something else?
Hi tiny-tim,
my teacher had told me that this was a quadratic equation. But I don't really know how to set that up. All I have now are these variables. Any help would be appreciated and thanks for letting me know of the signs which the forum integrates.

My teacher has given me sin(theta)=(square root) of 1-cos^2(theta)
and cos(theta) = xThe Attempt at a Solution
I'm a bit stuck, the part which I am up to is...
no i mean like on a slope. My teacher said that you don't need mass if you have M = mu. So on a 45 degree angle ramp. The delta x would be 30m. Then you would need you can cancel out the m's in a equation.
no time. Just are given angle, delta x, mu
