The length of a simple pendulum is 0.74 m and the mass of theparticle (the "bob") atthe end of the cable is 0.25 kg. Thependulumis pulled away from its equilibrium position by an angleof 9.05°and released from rest.Assume that friction can be neglected andthat the resultingoscillatory motion is simple harmonic motion.
(a) What is the angular frequency ofthemotion?
(b) Using the position of the bob at its lowest point asthereference level, determine the total mechanical energy ofthependulum as it swings back and forth.
(c) What is the bob's speed as it passes through the lowest pointofthe swing?
