A simple pendulum with mass m = 1.5 kg and length L = 2.51 m hangs from the ceiling. It is pulled back to an small angle of θ = 9.6° from the vertical and released at t = 0.

a) What is the angular displacement at t = 3.69 s? (give the answer as a negative angle if the angle is to the left of the vertical) (- The period of oscillation is 3.18s)

Answer #1

The bob will perform SHM and motion will start from Amplitude( It is pulled back and released).

At t=0, Bob will have maximum angular displacement.
