Listen up, you pointy-headed nerds.

An 3 meter (10ft), weighing 544kg (1200 lbs) White shark traveling through the water at 11 m/s (25mph) hits a kayaker weighing 136kg (300lb kayak+gear+ meatbag)  dead center. What is the force of the hit, and what is the acceleration of the kayaker?

If anyone cares to help control confounding factors such as force absorption of the kayak, and/or better estimates of weights/speeds, or mess with vectors... then have at.

I thought we weren't going public with this until we've done more of our own research first?

Don't forget to calculate in the surface tension of the kayak in the water as it is attempted to be lifted.  At what angle should the shark be attaching from in relation to the water line of the kayak? 

 

I know some toothy math  man is gonna nail this --debate will ensue

but I want to get my guess in early
I am gonna get in at -6 g's for force and 3+ for the person in the kayak at first launch

reasearch!? aint nobody got time for that. 

btw -I  stole that graph  -not a shark but heavy car  .. from this  below topic-which has some head hurting formulas for figuring it out

Yes! thanks for volunteering to do the surface tension and vector calculations!

Screw Mythbusters

This topic is for pointy headed nerds. I know that because it says so in the subject line.  Heck, even Triangualina found a graph of some sort.  The rule is that if you chose to introduce a variable to the problem, then you must at least attempt to solve your introduced variable. B&*ch @&& *&#$ !

LOL  I hereby withdraw my variable 

FTF comes into play as well. The Fecal Thrust Factor, varies on age of person, last THREE meals as opposed to merely breakfast, and of course sexual preferences.

So because I was screwing around in class is this a elastic or inelastic collision ...

I treated it as an elastic collision. But, I highly encourage you to take a giant calorimeter with you when you go out.  When you get hit by my hypothetical shark you can tell us how much kinetic energy was converted to heat.

No maths needed:

Force hit = "WTF!"
Acceleration = "Holy Shit!"

Them college classes ain't needed

This closely approximates my back of the napkin calculations.
