Question
A block of mass M = 109.0 kg on an inclined plane is attached to another block of mass m via a string, as in the figure below. The coefficients of static and kinetic friction for
the block and the incline are u, = 0.40 and uy = 0.20 and the plane is inclined 16.9° with horizontal.
(a) Determine the range of values for m, the mass of the hanging block, for which the block will not move unless disturbed, but if nudged, will slide down the incline.
