Physics help please. tension and im clueless?

Block 1 of m 2.0 kg and block 2 of m 3.0 kg are connected by a string of negligible m and are initially held in place. Block 2 is on a frictionless surface tilted at q = 31.0o. The coefficient of kinetic fricition between block 1 and the horizontal surface is 0.25. The pulley has negligible m and friction. Once they are released, the blocks move. What then is the tension in the string?
