URGENT: rotatonal KE Two astronauts each having a mass of 54 kg are connected by a 10 m rope of negligible mass. They are isolated in space, orbiting about their centre of mass at speeds of 3.7 m/s. Calculate the rotational energy of the two astronauts. A. 739.3 J B. 1478.5 J C. 29.6 J D. 317.9 J E. 369.6 J Which one is it????? I did: KE= 1/2 (I + I) omega ^2 and it turned out to be A. Is it correct???
