Can You Survive A Jump From A Building? [Video]

Kids, if I EVER catch you doing this you may be grounded for like 2 months. Meaning no Wii and no internet. GROUNDED.

Which this kind of guys was the first to return up with this crazy idea. ” I will be able to offer you 10 rubles in the event you jump off the building into the snow.” Really though, this seems so crazy – is it even real? First assumption is that it really is indeed real. However, I will do an easy video analysis simply to check. (after all using the smartest free video analysis tool – Tracker Video )

Nice try Russian video person. You tried to make it difficult to research this video, and I salute your efforts. The camera really moves around rather a lot. However, I am a master of Tracker Video. This is a plot of the vertical motion of the first jumper. It really is in distance units of 1 story.

Is it real? Well, it feels like a continuing acceleration of -4.86 stories/s2. If I guess this event occurs in the world with a free-fall acceleration of -9.8 m/s2, I will determine the height of one story.

Hmmmm….Two meters that just seems impossible (it’s not impossible, we used to bullseye wamprats back home and they aren’t much bigger than 2 meters). No really. Ok, let me try another jump and spot if I get similar accelerations.

For this jump, I get an acceleration of about -3.58 story/s2. This is able to put the height of a story at 2.7 meters. That seems a lot more likely. Within the US, a story for a commercial building might possibly be around 10 feet. However, let me do yet another jump to simply ensure. This last one gives a story height of 2.1 meters. Ok, I am moving on. The video is poor quality and the camera does indeed move around a little bit. The acceleration is continuing, so I assume that’s adequate. I’m going to choose a story height of a random 2.5 meters – that seems a bit low, but oh well. Which means that height of the building is around 13 meters.

Next question: can you do that? In fact you could. Remember Professor Splash? He jumped from a height of 10 meters and landed in water just 30 cm deep. It could be done. i’m really not going over the small print – but I do have a dangerous jumping calculator page . Here I show tips on how to determine the acceleration while landing.

Acceleration is the most important to avoiding injury. In step with NASA’s g-tolerance tests , somebody in standing position can handle about 18 g’s (170 m/s2) – for extremely short periods. So, what sort of accelerations would these crazy Russians experience? If the building is 13 meters tall and the snow is set 1.5 meters deep, then the acceleration can be just 7.6 g’s. Clearly survivable (but still don’t do it).
