Evaluate what fraction of its kinetic energy is rotational

Reference no: EM13552425

A yo-yo is made of two solid cylindrical disks, each of mass 0.051 and diameter 0.080 , joined by a (concentric) thin solid cylindrical hub of mass 0.0049 and diameter 0.012.

Part A: Use conservation of energy to calculate the linear speed of the yo-yo when it reaches the end of its 1.0 long string, if it is released from rest.

Part B: What fraction of its kinetic energy is rotational?
