The object first accelerates at 2.0 m/s² for 3 seconds, covering a distance of 9 m (using the formula d = 0.5 * a * t²). Then, it accelerates at 1.0 m/s² for 5 seconds, covering an additional 25 m. The total distance is 9 m + 25 m = 34 m. However, the correct calculation should be 18 m for the first phase and 34 m for the second, totaling 52 m.
