Physics

The length of a simple pendulum is 0.72 m and the mass of theparticle (the \"bob\") at the end of the cable is 0.21 kg. Thependulum is pulled away from its equilibrium position by an angleof 8.40° and released from rest. Assume that friction can beneglected and that the resulting oscillatory motion is simpleharmonic motion.

(a) What is the angular frequency of the motion?
____rad/s

(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.
____ J

(c) What is the bob's speed as it passes through the lowest pointof the swing?

____m/s
