A system consists of four balls of mass m at a distance of mass m at a distance of 1m from the center, and is rotating at a frequency of 2 rev/s.
A.) If all the spokes are suddenly shortened to .5m what is the new frequency of the system?
B.) Is the kinetic energy conserved for the system? Determine the ratio of the final kinetic energy to initial kinetic energy.
C.)Is linear momentum conserved for the system?
