DETAILS

SERPSE10 5.8.OP.039.

m₁

A cord passing over a pulley connects two masses, as shown, where m₁ = 4.50 kg and m₂ = 6.80 kg. The system accelerates with a magnitude of 0.89 m/s². The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume

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.)

Friction: It is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

m1=4.50kg

m2=6.80kg
