A merry-go-round has a mass of 
and radius of 
. How much net work is required to accelerate it from rest to a ration rate of 
revolution per 
seconds? Assume it is a solid cylinder.
A merry-go-round has a mass of 
. The wheel can be considered a uniform disk of mass 
and diameter 
. The potter then throws a 
chunk of clay, approximately shaped as a flat disk of radius 
, onto the center of the wheel. What is the angular velocity of the wheel after the clay sticks to it?
