Scene 7

In the this part of the scene, Ethan jumps across a large gap in the bridge and then smashes into the side of gap after the jump in order to make it across. Since the scene was in slow-mo, I sped it up and then performed a tracker analysis to determine Ethan's speed to be around 7-9 m/s when he hit the side of the gap. At this speed it seems reasonable for him to have cleared the gap and survived.

In this part of the scene Ethan is thrown off his feet because of an explosion and then hits a car. Looking at the tracker data Ethan was thrown at the car at a speed of 7.3 m/s which is not accounting for the shift of camera angle. Accounting for that shift the speed he impacted the vehicle is more like 9 m/s. Using data from the first link, the calculated velocity needed to kill a person on impact is 22 m/s.Since the tracker data shows that he is traveling at a lower velocity, that impact would not kill him.

Although this is the case, the heat from the explosion combined with the impact has a high chance of killing or severely injuring Ethan. With the speed that he was traveling combined with the sudden deceleration when he hit the car, impact might not kill him but would at least lead to some internal damage and broken bones. Additionally the heat from the explosion would severely burn Ethan and shrapnel might fly at him because of the explosion. This scene cannot be backed by physics.
