String tension

Two masses of 3.5 kg each, connected by a string, slide down a ramp making an angle of 34 deg. with the horizontal. The coefficient of kinetic friction between m1 and the ramp is .33. The coefficient of kinetic friction between m2 and the ramp is .18.

I know my acceleration is 3.41 m/s^2.

How do I determine the tension of the string? Please show steps. See the attached file for diagram.

Note 1. My keyboard does not have Greek letters. In the equations below, let the angle of the plane be b, the coefficient of friction for m1 be f1, and for m2 be f2.

Note 2. You correctly obtained a= 3.41 m/sec^2 for the acceleration by applying Newton's second law, 'net force = ...
