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
