Mass m = 14.5 kg is on a horizontal surface. Mass m = 8.68 kg hangs freely on a rope which is attached to the first mass. The coefficient of static friction between m and the horizontal surface is us = 0.537, while the coefficient of kinetic friction is uk = 0.169. m m, If the system is in motion with m moving to the left, then what will be the magnitude of the system's acceleration? Consider the pulley to be massless and frictionless. Submit Answer Incorrect.
