What is the final angular speed of the astronauts

Reference no: EM13274996

Two astronauts, each having a mass M are connected by a length of rope of length d have a negligible mass. They are isolated in space, orbiting their center of mass at an angular speed of w0. By pulling on the rope, one of the astronauts shortens the total distance between them to 0.507d. Treat the astronauts as point particles (in terms of their moments of inertia).

a) What is the final angular speed of the astronauts as a fraction/multiple of ?0 ? (E.g. If you find that the final angular speed is half the initial angular speed enter 0.5.) Use angular momentum conservation.

b) What work does the astronaut do to shorten the rope as a multiple/fraction of the quantity Md2?02 (which has dimensions of energy)?
