phi · Answer

are you asking how to do Part A or Part B?

anonymous · Answer

Part B. I got part A but idk if you need that for part B.

phi · Answer

displacement means the distance (in a straight line) between the start and end point.
In this case, it will be the diameter of the circle.  Any idea how to find the diameter?
