An object is at x = 0 at t= 0 and moves along the x axis according to the velocity-time graph in Figure P2.62. (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? (1) 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?
