Object A has a mass mA = 1.0 kg and is connected to mass mB = 0.25 kg with a massless and unstretcheble sting passing over a massless and frictionless pulley. Find the acceleration of object A if the coefficient of kinetic friction with the incline is 0.25. The height of the incline is 0.6 m and the length is 1.0 m. Assume g = 10 m/s2.
