Two ice-skaters, whose masses are 45 kg and 75 kg, hold hands and rotate about a vertical axis that passes between them, making one revolution in 3 s. Their centers of mass are separated by 1.7 m, and their center of mass is stationary. Model each skater as a point particle.

(a) Find the angular momentum of the system about it's center of mass.

(b) Find the total kinetic energy of the system.
