A person is swinging a ball of mass m above their head in a horizontal plane. When the ball is moving at a constant speed, the string forms an angle θ with respect to the horizontal. Assuming that the motion of point O is negligible and that the distance between the point O and the mass m is L, determine the speed of the ball.
