A ball is placed at the initial position with a direction arrow indicating its movement direction. Simulate the ball bouncing 3 times off the boundary walls following elastic collision physics (angle of incidence equals angle of reflection). The ball stops after the 3th bounce, with its final position at the wall where the last collision occurs. Only modify what the task requires; keep the background and any other element unchanged. Output one image showing the ball's final position, with the complete trajectory path drawn as an orange line showing the ball's route including all bounce points.
