Calculating Period and Frequency of a Pendulum

In this video, I walk through problem number 29 from chapter 11 of Giancoli Physics AP edition, focusing on oscillations and waves. We analyze a pendulum that makes 28 oscillations in 50 seconds, calculating its period and frequency. I encourage you to pause the video and try solving the problem on your own before we compare notes. The calculations involve basic dimensional analysis, and I provide step-by-step guidance to arrive at the answers. Giancoli Physics, AP Edition, 7th Edition, Chapter 11, Problem 29
