Question:

The automobile path shown in Figure is made up of straight lines and arcs of circles. The automobile starts from rest at point A. After it reaches point B, it travels at constant speed until it reaches point E. It comes to rest at point F.

(a) At the middle of each segment (AB, BC, CD, DE, and EF), what is the direction of the velocity vector?

(b) At which of these points does the automobile have an acceleration? In those cases, what is the direction of the acceleration?
