You are testing the friction between blocks and surfaces, and have devised the system shown in the figure, to test with different masses. Two blocks with mass m₁ = 75kg and m2 = 20kg are connected by a massless string over a frictionless and massless pulley. The angle of the incline is equal to 0 = 30°. The kinetic coefficient of friction between m₁ and the incline is μ = 0.23. The static coefficient of friction between m₁ and the incline is μ = 0.6. m1 Ө m2 The system is released from rest. It will either remain static, or start moving. Determine what happens and find the tension in the string and the frictional force for that condition. Note: depending on your values, the system could want to move either up or down the slope. Friction Casel= Tension Casel= N
