## Homework Statement

:[/B]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 phai 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!
