Solve the given question:
Question: A yo-yo is made of two solid cylindrical disks, each of mass 0.053kg and diameter 0.078m, joined by a (concentric) thin solid cylindrical hub of mass 0.0054kg and diameter 0.010m .
Question 1: Use conservation of energy to calculate the linear speed of the yo-yo when it reaches the end of its 1.1m long string if it is released from rest?
v =
Question 2: What fraction of its kinetic energy is rotational?
KErot/KEtot=
