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 θ from the vertical?Express your answer in terms of some or all of the variables m, L, and θ, as well as the acceleration due to gravity g. V = Lsin(θ) / sqrt(Lcos(θ) / g)v = Lsin(θ) / sqrt(Lcos(θ) / g)
