Question: A flywheel with mass m and radius r is rotating without friction at a given angular velocity, w. A semi-circle with the same mass

A flywheel with mass m and radius r is rotating without friction at a given angular velocity, w. A semi-circle with the same mass but unknown radius r2 is rotating (also without friction) in opposite direction with twice the angular velocity when it is dropped onto the flywheel. Due to friction between the two objects they quickly come to rest. What is the radius of the semi-circle? (1P) Assume that no external friction is acting.
