Two astronauts, each having a mass of 89.0 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 5.90 m/s. Treating the astronauts as particles, calculate each of the following.

Illustration Description:
- Two astronauts are shown connected by a rope with a length \(d = 10.0\) meters.
- The center of gravity (CG) is marked as the midpoint of the rope.
- Arrows indicate the circular motion of the astronauts around the CG.

(a) The magnitude of the angular momentum of the system:
\[ \text{5251 kg} \cdot \text{m}^2/\text{s} \]

(b) The rotational energy of the system:
\[ \text{3.09 kJ} \]

By pulling on the rope, the astronauts shorten the distance between them to 5.00 m.

(c) What is the new angular momentum of the system?
\[ \text{5251 kg} \cdot \text{m}^2/\text{s} \]

(d) What are their new speeds?
\[ \text{ m/s} \]

(e) What is the new rotational energy of the system?
\[ \text{ kJ} \]

(f) How much work is done by the astronauts in shortening the rope?
\[ \text{ kJ} \]
