This is an old video, but still interesting. In this video clip clip, Kobe Bryant jumps over a pool of snakes.You are more than likely thinking what i thought when I see that - this doesn't watch real. Really, it must be fake. Why would certainly Kobe jump over a pool of snakes? Isn't the dangerous (even if there to be no snakes in there he might hurt himself). Video clip analysis is needed. Is this fake or is that real?

This is an old video, however still interesting. In this video clip clip, Kobe Bryant jumps end a swimming pool of snakes.https://www.youtube.com/watch?v=QBJZXyfLrpUYou are most likely thinking what i thought as soon as I check out that - this doesn't look at real. Really, it need to be fake. Why would Kobe jump end a pool of snakes? Isn't the dangerous (even if there were no line in over there he might hurt himself). Video clip analysis is needed. Is this fake or is that real?

Start with my favourite – video analysis device (tracker). Use this to gain position time data.Step 1: gain the movie. I offered Mpeg Streamclip to get the movie in quicktime layout from the speed video. Over there are several ways to get video off youtube - that can be a short article for one more day (or you could just google it).Step 2: obtain some stuff to calibrate the video. Tracker video will give me how much (in pixels) points move. Yet how big is a pixel in actual life? I require to recognize the dimension of something. At first, i tried to discover the precise pool they provided in the video. Fail. Following I visited wikipedia to obtain the dimensions of Kobe Bryant entity. He is 1.98 meter tall.Step 3: analysis the video. Right here is the vertical movement of Kobe.

You are watching: Kobe jumps over pool of snakes

From this, i can display a couple of vital things. First, it is a parabolic graph. This indicates the acceleration is constant. Second, ns can achieve a value for this acceleration. It will certainly be twice the coefficient that the x>2 term. This way that the acceleration the Kobe while jumping is 9.56 m/s2. This is close sufficient to the supposed value that 9.8 m/s2 the the video seems real.Let me currently look in ~ the horizontal motion:
*
This is plainly a directly line indicating the the is no horizontal acceleration. This additionally is one indication of non-fakedness.What can be learned indigenous this analysis? Well, how far did the jump? He clearing the pool which is 12 feet in diameter. (I obtained the dimensions of the swimming pool after scaling the video clip according come the size of Kobe).How fast was he going once he jumped? Well, his horizontal velocity is 5.5 m/s. The initial vertical velocity (for the jump) deserve to be uncovered from the equation that motion:
*
So, the complete velocity (magnitude) will certainly be:
*
This is 17 mph - the is pretty fast.So, is that fake? ns guess not. Or probably it is really clever and advanced fake. Probably Kobe is a robot or cylon or something.
