A cord passing over a pulley connects two masses, as shown, where m, = 4.30 kg and m, = 6.00 kg. The system accelerates with a magnitude of 0.64 m/s². The coefficient of kineti friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m2 m, 35.0° 35.0° (a) What is the coefficient of kinetic friction? Draw free-body diagrams for both blocks and write Newton's second-law equations in the x and y-directions. Condense your four equations two by substituting, and solve the system of two equations for the two unknowns, Hy and T. (b) What is the tension (in N) in the cord?
