A ball at height 13.3m with initial upward velocity 0.7 m/s falls under gravity 6.1 m/s² and bounces on ground with elasticity 0.70. Only modify what the task requires; keep the background and any other element unchanged. Output one image at each endpoint of the trajectory — at the top (peak) of every bounce and at the bottom each time the ball hits the ground and rebounds — each with a velocity arrow showing direction and magnitude, until the ball comes to rest.
