1. The problem statement, all variables and given/known data In Fig. 6-50, block 1 of mass 1.3 kg and block 2 of mass 2.5 kg are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at θ = 31o. The coefficient of kinetic friction between block 1 and the horizontal surface is 0.16. The pulley has negligible mass and friction. Once they are released, the blocks move. What then is the tension in the string? 2. Relevant equations Maybe T-muFN=m1a Fn=m1a=12.74 Combined equation: T=-m2a+m2gsin(theta) 3. The attempt at a solution My T came out to be 4.7N but since it is smaller than my Fn I know it can't be correct. What equation will give me the correct answer?
