1. Homework Statement :

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

Homework Equations



theta = A sin (w t + phai)

The Attempt at a Solution



Does pahi represent the period? And how do I get it?
Do I derive theta once & twice? And why?
How do I get w & A?

Thank you!

FChebli: You must list relevant equations yourself, and show your work; and then someone might check your math. We are not allowed to provide answers here. We can only check your math, after you do all of the work. What is BoB? Parameter phai is probably phase angle.
