The pendulum in a grandfather clock makes one complete swing every 2 seconds. The maximum angle that the pendulum makes with respect to its rest position is 6. We know from physical principles that the angle between the pendulum and its rest position changes in simple harmonic fashion. Find an equation that describes the size of the angle as a function of time (in seconds). (Take t = 0 to be a time when the pendulum is vertical and assume the pendulum is swinging toward its positive maximum angle.) Be sure to put parenthesis around your argument. ow
