6. A ball of mass mı=2 kg and a block of mass m2=5 kg are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as in the Figure. The angle of incline, 0, is 60°. (a) The block lies on a frictionless incline. Draw free-body diagram of the objects. Find the magnitude of the acceleration of the two objects and the tension in the cord. (b) The block lies on a rough incline plane which has a coefficient of kinetic friction (µx) of 0.35. Draw free- body diagram of the objects. Find the magnitude of the acceleration of the two objects and the tension in the cord. in)
