73. Block A, with weight 3w,slides down an inclined plane
S of slope angle 37 at a constant speed while plank B,
with weight w,rests on top of A.The plank is attached
by a cord to the walt.(a) Draw a diagram of all the forces
acting on block A. (b) If the coefficient of kinetic
friction is the same between A and B and between S and
A,determine its value.
