1. The problem statement, all variables and given/known data Consider a conical pendulum that consists of a bob on one end of a string of negligible mass with the other end of the string attached to a point on the ceiling, as shown. Given the proper push, this pendulum can swing in a circle at a given angle, maintaining the same distance from the ceiling throughout its swing. If the mass of the bob is , the length of the string is d, and the angle at which it swings is θ, what is the speed (v) of the mass as it swings? [Hint: Find the vertical and inward radial components of the string’s tension.] 2. Relevant equations FR = (mv2)/r 3. The attempt at a solution For [tex]\Sigma[/tex]Fy I got FT = mg/cos θ I said r = dsinθ And for [tex]\Sigma[/tex]FR I got FTdsin2 θ = v2 Plug in mg/cos θ for FT and sqrt(gd tanθ sin θ)= v Is that right?
