Two ice-skaters, whose masses are 45 kg and 75 kg, holdhands and rotate about a vertical axis that passes between them,making one revolution in 2 s. Theircenters of mass are separated by 1.7 m, and their center of mass isstationary. Model each skater as a point particle.
(a) Find the angular momentum of the system about their center of mass.
(b) Find the totalkinetic energy of the system.
