  • The image displays a two-dimensional coordinate system with a horizontal axis labeled "x" and a vertical axis implied by the vertical displacement, showing unit vectors \(\mathbf{i}\) and \(\mathbf{j}\) at the origin labeled "O".
  • A rectangular structure labeled "Bridge" is shown above the horizontal axis, and the distance between the bridge and the river surface is indicated by a vertical double-headed arrow labeled "77\ m".
  • A straight line, representing the path of a projectile, starts at the edge of the bridge and slopes downwards to the level of the "River".
  • The vertical side of the path is labeled "r" (likely representing the initial vertical displacement or range), and the horizontal distance it falls to the river is labeled "y".
  • The context suggests this diagram illustrates the coordinates and displacement for an object projected from the bridge over the river.
