A pendulum is held at an angle of 30 as shown in figure 1 and then released. The length from the top of the string to the centre of the spherical pendulum is 0.25 m. Calculate the maximum velocity of the pendulum: (i) using equations for simple harmonic motion. (ii) using the principle of conservation of energy. In the discussion section of the report you should discuss any differences between the calculations. 60g 30 30 Figure 1.
