Answer:
1.the object is moving with a constant speed
2.Acceleration from A to B = change in velocity/change in time = 25-0/3-0 = 8.33 m/s<sup>2</sup> ... Average velocity from C to D = (initial velocity + final velocity)/2 = 15-0/2 = 7.5 m/s. Distance covered in the region BCFE = (1/2)(sum of parallel sides)(distance between them) = 20 m.
