A simple pendulum consists of a spherical bob of mass 0.052 kg and diameter 1.1 cm attached to a thread of length 920 mm.
b) The bob is released at rest with the thread taut at an angle of 5 degrees to the vertical. Calculate:
i) the amplitude of the oscillation
The Attempt at a Solution
Am I right in saying it is tan(5) * 920 = 80mm round to 2 sig fig?
