Today what I
am going to share is an easy mathematical calculation which reveals a
surprising fact; this thought came into my mind just yesterday while I as
drinking tea standing in a tea stall and some customers arrived there in their bikes.

We all know that
there are lots of fictitious things are shown in many movies, like…the villain
flies in the sky and travels 10ft-20ft after getting a kick from the hero,
sometime heroes holds the legs of villains and throws him as we can throw
cricket bats, this is the reason in the beginning of the movies you can see the
preface…”all these characters are fictitious…..”

Now let me
tell you what I am going to share today…

I am going
to calculate the weights (approx.) of the heroes from action movies…

The scene
is...a villain in a bike comes towards the hero with the intention to hit the
hero with his fast moving bike, hero doe not move from his position and
standing still the hero lifts his one leg kicks the front portion of the moving
bike and receiving kick from the hero the rider fell along with the bike in the
same direction that he was coming.

This is a
very common scene we have watched in many movies, so now my calculation is….

The average
weight of a bike is 100kg.

The average weight
of a villain is 60 kg

Total weight
is = 160kg.

The speed of
the bike is 40km/hr = 11.11m/s

Then the momentum
(mass × velocity) of the system (Bike+Hero) is

160 ×
11.11 kg-m/s= 1777.6 Kg-m/s

To stop this
momentum the equal or greater amount of momentum is needed, let me consider the
force exerted by the kick of the hero is equal to this force, now the speed of
the moving leg is hardly 2km/s means 5.55m/s, so what should be the weight of
the leg…

__Now equaling both sides__

Weight of
the leg × speed of leg
= weight of the system× speed of
the system

Putting the values we get…

Weight of the leg × 5.55m/s = 160kg
× 11.11 m/s

=1777.6 kg-m/s

Therefore, the weight of the leg = 1777.6kg-m/s ÷ 5.55m/s

= 320kg

(m/s in up and down will cancel each other)

So this should be the weight of a leg
of a hero (Lead character) who can stop a moving bike which weights 100kg and
speed 40km/hr with a villain whose weight is 60kg.

If 320kg is the weight of one leg then
try to guess what should be the weight of the whole body…I think approximately
1600kg.

This type of
calculation is actually ad by “impulsive Force” theory of Physics, but don’t worry
though I have made this one easier but it will not affect the calculation much.
