Answer: 4.28 m.
Explanation: To determine the x-position of a particle that is 4.28 m directly above the origin, we need to consider that the origin is typically located at the point (0,0) on a coordinate system.
Since the particle is directly above the origin, it means that its y-coordinate is 4.28 m. However, the question specifically asks for the x-position.
In this case, we can assume that the particle is located on the x-axis, which means its y-coordinate is 0. Therefore, the particle is at a horizontal distance of 4.28 m from the origin.
Hence, the x-position of the particle is 4.28 m.
