Two astronauts (Fig. P10.67), each having a mass M, are connected by a rope of length d having negligible mass. They are isolated in space, orbiting their center of mass at speeds v. Treating the astronauts as particles, calculate (a) the magnitude of the angular momentum of the two-astronaut system and (b) the rotational energy of the system. By pulling on the rope, one of the astronauts shortens the distance between them to d/2. (c) What is the new angular momentum of the system? (d) What are the astronauts new speeds? (e) What is the new rotational energy of the system? (f) How much chemical potential energy in the body of the astronaut was converted to mechanical energy in the system when he shortened the rope?

A war-wolf, or trebuchet, is a device used during the Middle Ages to throw rocks at castles and now sometimes used to fling pumpkins and pianos. A simple trebuchet is shown in Figure P8.89. Model it as a stiff rod of negligible mass 5.00 m long and joining particles of mass m1 = 0.120 kg and m2 = 60.0 kg at its ends. It can turn on a frictionless horizontal axle perpendicular to the rod and 14.0 cm from the particle of larger mass. The rod is released from rest in a horizontal orientation. Find the maximum speed dial the object of smaller mass attains. FigureP8.89

Luc, who is 1.80 mm tall and weighs 950 NN, is standing at the center of a playground merry-go-round with his arms extended, holding a 4.0 kgkg dumbbell in each hand. The merry-go-round can be modeled as a 4.0-mm-diameter disk with a weight of 1500 NN. Luc's body can be modeled as a uniform 40-cmcm-diameter cylinder with massless arms extending to hands that are 85 cmcm from his center. The merry-go-round is coasting at a steady 35 rpmrpm when Luc brings his hands in to his chest. Afterward, what is the angular velocity, in rpmrpm, of the merry-go-round? The answer is not 31.6 rpm.
