A clock pendulum oscillates at a frequency of 2.5 Hz. At t = 0, it is released from rest starting at an angle of 15° to the vertical. Ignoring friction, what will be the position (angle) of the pendulum at (a) t = 0.25 s, (b) t = 1.60 s, and (c) t = 500 s? [Hint: Do not confuse the angle of swing θ of the pendulum with the angle that appears as the argument of the cosine.]
