a 5 kg concrete block accelerates down a 34 degree slope at 4.2m/s^2. Find the coefficient of friction between the block and the slope.

The net force along the slope that produces the acceleration is

F = M g sin 34 - u M g cos 34 = M a
where u is the coefficient of friction.

M cancels out-- you don't need to know it. You can solve for u

I get u = 0.158, but don't trust my math. Check my thinking and do the numbers.
