Generate an image showing the scene at that instant, where the original annotations (coordinate axes and any initial velocity arrows) have been cleanly removed while the background, ground, sky, and all scene lighting remain completely unchanged from the input. Show each object at its correct position at t = 4.0 s — each object must retain its exact texture, material, size, and shape. For each moving object, overlay a borderless orange arrow starting from the object's center pointing in its instantaneous velocity direction, with a label \"v = X.XX\" (speed value, no unit). If an object is at rest, show \"v = 0\" with no arrow. Keep the same viewpoint as the input image — no zoom, no rotation, no crop.",

For each moving object, overlay a borderless orange arrow starting from the object's center pointing in its instantaneous velocity direction, with a label \"v = X.XX\" (speed value, no unit). If an object is at rest, show \"v = 0\" with no arrow. Keep the same viewpoint as the input image — no zoom, no rotation, no crop.",
