A particle is sliding with acceleration 3 down a line of greatest slope of a fixed plane. The plane is inclined at 40 degrees to the horizontal.
Calculate the coefficient of friction between the particle and the plane.
I tried drawing a diagram and found that you haven't got the mass or the driving force when I tried to calculate, so I couldn't rearrange. Also I tried to cancel out the masses but you can't do that for the normaL and still leaves you with the driving force. Any ideas?

There is no "driving force". It is sliding under gravity. Call the mass m.

if it helps you can let the mass be 1 kilogram
