A cord passing over a pulley connects two masses, as shown, where m₁ = 3.30 kg and m₂ = 6.30 kg. The system accelerates with a magnitude of 1.09 m/s². 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, not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m₁ 35.0⁰ 35.0° m₂ (a) What is the coefficient of kinetic friction?

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
