Find the magnitude of the force necessary to move the blocks at constant speed. If the angle q is increased until the object will just slide without accelerating, then the force is given by fs = mg sin q. The coefficient of friction mu is defined by f/FN. Since FN = mg cos q, or mu = (mg sin q)/(mg cos q) or mu = tan q. Therefore, we can determine mu by allowing the block to slide at a uniform speed down the incline.
