A clock pendulum oscillates at a frequency of 2.5 Hz . At t=0, it is released from rest starting at an angle of 16 ∘ to the vertical.
a) Ignoring friction, what will be the position (angle in radians) of the pendulum at
t = 0.25 s ?
b) Ignoring friction, what will be the position (angle in radians) of the pendulum at t = 2.00 s ?
c) Ignoring friction, what will be the position (angle in radians) of the pendulum at
t = 520 s ?
