Two blocks are connected by a massless rope over a massless, frictionless pulley, as shown in the figure. The mass of block 2 is 𝑚2=10.9 kg , and the coefficient of kinetic friction between block 2 and the incline is 𝜇𝑘=0.200 . The angle 𝜃 of the incline is 31.5° . If block 2 is moving up the incline at constant speed, what is the mass 𝑚1 of block 1?
