    If the vehicle maintained a constant velocity and there was no air resistance, the diver would enter the pool.

    In the real world, air resistance would cause the diver’s velocity to decrease relative to the vehicle and thus the second panel is a probable outcome.

      I don’t think you can assume constant velocity. 16 forward movement lines on the top vs 13 on the bottom so it’s moving at 81.25% speed in the bottom compared to the top.

      It would depend on the speed, and any speed a person could actually stand an jump from is likely slow enough they still land in the pool.

      The diver would feel the same wind while in the air as while standing on that elevated diving board. He would recognize the strong 70Mph wind, and jump forward to counteract it.

        He wouldn’t be casually standing on the board at 70 mph either, so any wind strong enough to push him off the back would make it really hard to stand and dive in the first place.

        He is exerting force on the diving board to stay in position. Gripping with his feet, and leaning.

        Sure when you jump you.would.natutslly try to compensate, but I don’t think you’d land where you hope, it would be very hard to gauge the needed force, or even produce it.

      You wouldn’t drive an RV with a pool on the top very fast at all. It’d be a dangerous tipping hazard on any turn, and sudden acceleration or deceleration would cause the water to spill out.

      Assuming they’re not going 80, and more likely not even 55, the diver would have more than enough force to jump forward into the water.

      I doubt they are fast enough to blow him that far off. My bet would be that he falls flat on the middle of that board.

      Yeah, air resistance and friction from the road are the primary reason why the car’s engine has to keep running.
