Answer to Question #151116 in Physics for its me gel

Question

Solve the problems below and show the complete solution.

Strong winds can apply a significant enough force to tall skyscrapers to set them into a back-and-forth motion. The A of these motions is greater at the higher floors and barely observable for the lower floors. It is said that one can even observe the vibrational motion of the Sears Tower in Chicago on a windy day. As the Sears Tower vibrates back and forth, it makes about 8.6 vibrations in 60sec. Determine the frequency and the period of vibration.

Answer 1

$$f=\frac{8.6 }{60}=0.14\ Hz\\T=\frac{60 }{8.6}=7.0\ s$$
