A conical pendulum consists of a bob (small mass at end of massless rope) that moves in a horizontal circle at constant speed (the cord sweeps out a cone as the bob rotates). Here the angle θ = 18.92°, the length l= 2.59 m, and the bob has an unknown mass. (a)Find the speed of the bob. (b)Find the periodof the motion
