Final answer:
The displacement cannot be determined without additional information.
Step-by-step explanation:
The displacement of an object can be determined by finding the change in position between two points in time. In this case, the object undergoes displacement between t=2.0s and t=8.0s. To find the displacement, we need to subtract the initial position from the final position.
Since we do not have additional information about the initial position, it is not possible to determine the displacement without additional information. Therefore, the correct answer is (a) The displacement cannot be determined without additional information.
