The length of a simple pendulum is 0.75 m and the mass of the
particle (the “bob”) at the end of the cable is 0.26 kg. The
pendulum is pulled away from its equilibrium position by an angle
of 9.2° and released from rest. Assume 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,
determine the total mechanical energy of the pendulum as it swings
back and forth. (c) What is the bob’s speed as it
passes through the lowest point of the swing?
