Hello. I have attached an image of a free body diagram of a car traveling up a ramp at 30 degrees. I was wondering if anyone can help me determine the sumation of forces in the X and Y direction.(adsbygoogle = window.adsbygoogle || []).push({});

I understand that the forces in the Y-direction must be equal to zero or else the car will not stay on the ground. This is the formula I have come up with for this problem:

u = coeff. of friction

FN = mg / cos30

Fu = u x FN

F = force the car is moving under its own power

Sum of Forces in Y direction: FN x cos30 - mg = 0

Is this the correct equation for finding the forces in the Y direction?

Sum of Forces in X direction: F - Fu - (mg x sin30) = ma

Is this the correct equation for finding the forces in the X direction?

Any help would be appreciated. Thank you!
