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 Hk = 0.2. When the system is released, the 200 g block will begin to travel upwards. 1. After it is released, what is the acceleration of the 200 g block? 2. If the 200 g block starts at rest, what is the average power supplied to the pulley as the 200 g block travels 10 cm upwards?

![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 Hk = 0.2. When the
system is released, the 200 g block will begin to travel upwards.
1. After it is released, what is the acceleration of the 200 g block?
2. If the 200 g block starts at rest, what is the average power supplied to the pulley as the 200 g block
travels 10 cm upwards?
