Problem 2. Two astronautes each having a mass of 80 kg, are connected by a 12.0 m rope of negligible mass. They are isolated in space, orbiting their center of mass at speeds of 6.00 m/s. (a) Calculate the magnitude of the angular momentum of the two-astronaute system. (b) Calculate the total energy of the system. (c) By pulling on the rope, one astronaut shortens the distance between them to 6.00 m. What is the new angular momentum of the two-astronaut system? (d) Verify that the total mechanical energy is not conserved. (e) Notice that there are no external forces on the system. So, what happened to the lost energy?

A 87.9 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.53 rad/s. A monkey drops a 8.97 kg bunch of bananas vertically onto the platform. They hit the platform at 4/5 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 20.7 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform. Find the angular velocity of the platform with its load. Model the platform as a disk of radius 1.65 m.
