Question

The bent flat bar rotates about a fixed axis through point O. The angle can be found at any instant
according to this relation 8 = π * sin(t), where 9 is in rad and it is in seconds. At this instant, determine
the instantaneous velocity and acceleration of point A. Note: w=0, a = ö. Also, you must change the
angle from (Degree) to (Rad)

This question came up on my homework and I am having a lot of trouble with it. I know how to answer the first part (part a) through antidifferentiation but after that the two parts b and c are very unfamiliar and I have no idea where to start. Any tips? The velocity at time t of an object moving along an axis is t^3 − 3t. (a) Compute the net displacement between t = 0 and t = 3. (b) During what time intervals was it moving forward (resp. backward)? (c) What was its total distance traveled?
