Two masses, each 100 grams, are 30 cm connected by an effectively massless rubber band and thrown in the air. m m Initially, the rubber band is stretched to 30 cm as the masses rotate about their center of mass making 7 revolutions each second. The rubber band then pulls in the masses, contracting to 20 cm. How many revolutions per second do the rotating masses make after this contraction?
