Two blocks XXX (mass 10 kg) and YYY (mass 4 kg) are joined by a light inextensible string passing over a smooth pulley at the top of a fixed wedge. Block X X\,X rests on a smooth face inclined at 60∘ 60^\circ\,60∘ to the horizontal. Block Y Y\,Y rests on a rough face inclined at 30∘ 30^\circ\,30∘ to the horizontal. The coefficient of friction between block Y Y\,Y and the surface is 0.5. The system is released from rest with the string taut.
Find the tension in the string.
Find the acceleration of the system and the direction of travel.
