Find the heights of the pendulum

Reference no: EM13321336

Let a coil wand pendulum start swinging with an angle of 30 degrees with the vertical. After it passes through the magnet gap, the pendulum rises to the level which makes 20 degrees with the vertical. If the length from the center of the mass of the pendulum to the pivot is 30 cm,

A) Calculate the heights of the pendulum at the start and final positions and

B)What is the energy lost by the pendulum? Assume the mass of the pendulum by 80 grams.
