Q2) The bent flat bar rotates about a fixed axis through point O. The angle can be found at any instant
according to this relation = sin(t), where is in rad and t is in seconds. At this instant, determine
the instantaneous velocity and acceleration of point A. Note: w=0, a = 0. Also, you must change the
angle from (Degree) to (Rad)
