Final answer:
To determine the new position of a ball after a displacement of 20 m, the initial position must be known. Assuming the initial position is at the origin, the new position would be 20 m.
Step-by-step explanation:
If a ball undergoes a displacement of 20 m from its initial position, to determine the new position, we would need to know the initial position of the ball. Assuming that the initial position is the origin (0 m), moving 20 m from the origin would place the ball at a new position of 20 m. Therefore, the correct answer is C) 20 m if the initial position is the origin. However, without a diagram or additional context indicating the initial position, the question cannot be answered definitively.
