1. The problem statement, all variables and given/known data Consider the conical pendulum, a mass on the end of a string, with the other end of the string fixed to the ceiling. Given the proper push, this pendulum can swing in a circle at an angle theta of 25.5 degrees with respect to the vertical, maintaining the same height throughout its motion. If the mass of the pendulum M is 14.6 kg and the length of the string L is 0.5 m, what is the speed of the mass as it swings? 2. Relevant equations v = (coefficient of static friction x Rg)^1/2. R = .215 m I am not sure how to find the coefficient of static friction here, any help is appreciated.
