The length of a simple pendulum is 0.74 m and the mass of the particle (the "bob") at the end of the cable is 0.25 kg. The pendulum is pulled away from its equilibrium position with an angle of 9.05° and released from rest. Suppose that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion.
a) What is the angular frequency of the motion?
b) Using the position of the bob at its lowest point as the reference level, decide the total mechanical energy of the pendulum as it swings back and forth.
c) What is the bob's speed as it passes during the lowest point of the swing?
