Explain your reasoning in a well organized paragraph-length response.

A heavy rope is set over a small, ideal pulley so that one end is a distance y higher

than the other, as shown in the diagram. The rope has total length L and a mass-tolength ratio of µ (which would be measured in kilograms per meter). Suppose that

the rope is released from rest in this configuration.

I need part b and I believe its on chegg
