BoB released from rest, L = 102 cm, theta = +-5 degrees, g = 9.81 m/s2
assume a SHM
(I) Determine the angle theta after 1.6 s
(II) Determine the magnitudes of velocity & acceleration of the BoB at 1.6 s
theta = A sin (w t + phai)
The Attempt at a Solution
Does phai represent the period? And how do I get it?
Do I derive theta once & twice? And why?
How do I get w & A?
