In the mass-pulley system below, the pulley is yo-yo shaped; i.e. consists of a lightweight axle (on which the string rests) with a radius of 2 cm connecting two 4 cm radius disks, each with a mass of 50 g. The coefficient of kinetic friction between the 500g block and the surface is μk = 0.2. When the system is released, the 200 g block will begin to travel upwards.
