Two blocks of masses m(1)=1 kg and m(2)=...

Two blocks of masses `m_(1)=1 kg and m_(2)=2 kg` are connected by a string and side down a plane inclined at an angle `theta=45^(@)` with the horizontal. The coefficient of sliding friction between `m_(1)` and plane is `mu_(1)=0.4,` and that between `m_(2)` and plane is `mu_(2)=0.2.` Calculate the common acceleration of the two blocks and the tension in the string.
