Now we have a rod-shaped space station of length 648 m and mass 9.09 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 1.06 rpm. If the length of the rod is reduced to 453 m, what will be the new rotation rate of the space station?   2. A diver of mass 66.5 kg stands on one end of a diving board of mass 24.1 kg, as shown in the diagram. Everything is in equilibrium (since nothing is moving). What is the magnitude of the support force on the opposite end of the diving board?

1. Now we have a rod-shaped space station of length 648 m and mass 9.09 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 1.06 rpm. If the length of the rod is reduced to 453 m, what will be the new rotation rate of the space station?

 
2. A diver of mass 66.5 kg stands on one end of a diving board of mass 24.1 kg, as shown in the diagram. Everything is in equilibrium (since nothing is moving). What is the magnitude of the support force on the opposite end of the diving board?
For Question 9:

The diagram depicts a diving board setup with a person standing at the edge of the board. Key measurements are specified:

- The distance from the base of the ladder to the point directly below the diver is labeled as 1.00 meter.
- The distance from this point to the edge of the diving board where the person is standing is labeled as 2.00 meters. 

This setup may be used to analyze problems related to physics, such as analyzing forces, moments, or equilibrium.
