Two ice skaters, whose masses are 55 kg and 85 kg, hold hands and rotate about a vertical axis that passes between them, making one revolution in 2.5 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 and find (a) the angular momentum of the system about their center of mass and (b) the total kinetic energy of the system. 0.12 kJ. s and 0.05 kJ 0.24 kJ. s and 0.21 kJ 0.14 kJ. s and 0.31 kJ 0.24 kJ. s and 0.31 kJ
