Yes, I have drawn a FBD with x and y components that is perpendicular to the ramp. I used the Fg to find the x by going Fgsin30°. Which would be the same as Fn. Where would I go from this step?

Homework Statement A 5.0kg concrete block accelerates down a 34° slope at 4.2m/s^2. Find the coefficient of friction between the block and the slope. Homework Equations Fg=5*9.8=45 x=45sin30 y=45cos30 The Attempt at a Solution a=(mgsinθ-Ff)/m → Ff=mgsinθ-ma Thanks
