The length of a simple pendulum is 0.79 m and the mass of theparticle (the "bob") at the end of the cable is 0.24 kg. Thependulum is pulled away from its equilibrium position by an angleof 8.50 degrees and released from rest. Assume that frictioncan be neglected and that the resulting oscillatory motion issimple harmonic motion.
(a) What is the angular frequency of the motion?
(b) Using the position of the bob at its lowest point as thereference level, determine the total mechanical energy of thependulum as it swings back and forth.
(c) What is the bob's speed as it passes through the lowest pointof the swing?
