(a) For the yo-yo like cylinder of Example
10 19, we saw that the downward acceleration of its cm was  . If it starts from
rest, what will be the cm velocity after it has fallen a distance h i (b) Now
use conservation of energy to determine the cylinder’s c m velocity after it
has fallen a distance h, starting from rest.
