We have a rod-shaped space station of length 1419 m and mass 8.35 x 10^6 kg, which can change its length (kind of like an old-fashioned telescope), without changing its overall mass. Suppose that the station is initially rotating at a constant rate of 1.82 rpm. If the length of the rod is reduced to 1.82 m, what will be the new rotation rate of the space station?

A. 8.7 rpm

B. 2.32 rpm

C. 7.25 rpm

D. 2.9 rpm

A space station in the shape of a uniform disk (mass 6.42x105 kg, radius 150 m) rotates with period 33.6 seconds. There are also 809 astronauts (whom you can treat as point particles) working inside the space station, each of mass 199 kg, and all standing on the outside rim and rotating with the station. Now, all the astronauts move to a conference room at the very center of the space station. Find the new period of the rotation of...

A uniform rod of mass 3.40×10−2 kg and length 0.410 m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.190 kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 5.50×10−2 m on each side from the center of the rod, and the system is rotating at an angular velocity 28.0 rev/min ....
