What is the new rotational energy of the system

Reference no: EM13547432

Two astronauts, each having a mass of 88.0 kg, are connected by a 10.0 m rope of negligible mass. They are isolated in space, moving in circles around the point halfway between them at a speed of 4.30 m/s. Treating the astronauts as particles, calculate each of the following.

(a) the rotational energy of the system By pulling on the rope, the astronauts shorten the distance between them to 5.00 m.

(b) What are their new speeds?

m/s

(d) How much work is done by the astronauts in shortening the rope?
