Two astronauts, each having a mass of 74 kg, are connected by a 8.53 m rope of negligible mass. They are isolated in space, orbiting their center of mass at speeds of 4.08 m/s. Calculate the magnitude of the initial angular momentum of the system by treating the astronauts as particles. Answer in units of kg m2 /s. 017 (part 2 of 4) 10.0 points Calculate the rotational energy of the system. Answer in units of J. 018 (part 3 of 4) 10.0 points By pulling the rope, the astronauts shorten the distance between them to 4.18 m. What is the new angular velocity of the astronauts
