Frictionless, massless pulley - B As shown in the Figure, two blocks are connected by a rope with negligible mass, over a massless and frictionless pulley. Block A weighs 160 N and moves on the inclined plane wit an inclination angle e=30°. The coefficient of kinetic friction between block A and the incline is µk=0.25. (Take g = 10 m/s²) a) If block A slides down the incline at a constant speed, what is the weight of block B? b) If block B weighs 30 N, what is the acceleration of block A? m/s?
