Question

A clock pendulum oscillates at a frequency of 2.5Hz . Att=0, it is released from rest starting at an angle of 11?to the vertical.

a.Ignoring friction, what will be the position (angle in radians) of the pendulum at t = 0.35s ?

b. Ignoring friction, what will be the position (angle in radians) of the pendulum at t = 2.80s ?

c. Ignoring friction, what will be the position (angle in radians) of the pendulum at t = 540s ?

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

So, if you visualize the pendulum, it starts at 11
