A bob of mass m is suspended from a fixed point with a massless string of length L (i. e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ.
What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle from the vertical?
How long does it take the bob to make one full revolution (one complete trip around the circle)?
Express your answer in terms of m, L, θ and acceleration due to gravity g.
