Physics · Laws of Motion
Consider two bodies connected by an inextensible string passing over a frictionless pulley attached to the edge of a horizontal table. A body of mass m1 rests on the table, and another body of mass m2 hangs freely. If μ is the coefficient of kinetic friction between mass m1 and the table surface, the magnitude of the acceleration 'a' of the system when released is given by:
