An object is at x = 0 at t = 0 and moves along the x axis according to the velocity–time graph in figure p2.50.(a) what is the object’s acceleration between 0 and 4.0 s? (b) what is the object’s acceleration between 4.0 s and 9.0 s? (c) what is the object’s acceleration between 13.0 s and 18.0 s? (d) at what time(s) is the object moving with the lowest speed? (e) at what time is the object farthest from x = 0? (f) what is the final position x of the object at t = 18.0 s? (g) through what total distance has the object moved between t = 0 and t = 18.0 s?
