46. • A pendulum is constructed by attaching a small metal ball to one end of a 1.25-m-long string that hangs from the ceiling (Figure 6-44). The ball is released when it is raised high enough for the string to make an angle of 30.0° with the vertical. How fast is it moving at the bottom of its swing? Does the mass of the ball affect the answer? Example 6-8 1.25 m 30° V = ? Freedman, College Physics, 3e, 2021 W. H. Freeman and
