Three-month falling from the top of Everest?

Last day my friend told me that there are places where you fall for three months from Everest. What's your thought on that. So I made this post to check out that "Myth". 

Data we will need

  • Everest's height = 8,848m ( m = meters) [From the top to the very bottom level]
  • If a man fell from that top, he'd fall due to the gravitational acceleration ( g.acceleration = g) 


Lets do the MATH


S = Ut + 1/2 at^2
S = distance fell

U = Initial speed/velocity , in this case it's zero. If some one gave a pull the falling would be even shorter ( So i Use zero as the initial speed.

a = acceleration. In our case it's the gravitational acceleration which equals to "g". We can use 10 as the value of "g"

t = Time it took for the falling. We do this little math to find out this time. 



S = Ut + 1/2 at^2
8,848 = 0*t + 1/21* 10^2                                             [^2 = power of two]
t = 42.06 s. 

[ I used some simple Maths here,  It is the equation you find in "Motion" of physics. ]
What? Yeah. It's quite unbelievable, but it just takes 42.06 seconds to fall from the top of the Top of the Everest.

Less than 1 minute. Interesting huh?
