Problem
Two blocks, A of mass 4kg and B of mass 2kg, are connected by a light inextensible string and placed one behind the other on the same rough incline which makes an angle of 35∘ with the horizontal. The coefficient of kinetic friction between each block and the plane is 0.18. The system is released from rest and begins to slide down the incline.
(a) Write the equation of motion for each block along the incline.
(b) Hence determine the common acceleration of the two-block system. (Take g=9.8ms−2.)
