What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle 0 from the vertical? (Figure 1)A bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a Express your answer in terms of some or all of the variables m, L, and 0, as well as the free-fall acceleration g. pendulum). You are to investigate the motion in which View Available Hint(s) Figure
