Textbook Question
Chapter 15, Problem 45P
A performer seated on a trapeze is swinging back and forth a period of 8.85 s. If she stands up, thus raising the center of mass of trapeze + performer system by 35.0 cm, what will be the new period of the system? Treat trapeze + performer as a simple pendulum.

2. In class, we discussed several different flow scenarios for which we can make enough
assumptions to simplify the Navier-Stokes equations enough to solve them and obtain
an exact solution. Consulting the cylindrical form of the Navier-Stokes equations copied
