Question

A cord passing over a pulley connects two masses, as shown, where m? = 4.30 kg and m? = 7.00 kg. The system accelerates with a magnitude of 0.98 m/s". The coefficient of kinetic 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.) (a) What is the coefficient of kinetic friction? (b) What is the tension (in N) in the cord?
