Tis simple:


The grey blocks are of mass 1kg and the red one 2kg... the force F is 35N...all surfaces have coeff. of friction .5.

Angle A=37*.

Obviously, find the accn. of the grey block.

    5/4 in that case?

    maybe the question was better with F=25...one wouldn't have thought of the fact that the length constraint is applicable only for a positive value of tension
