Aim: To understand the physics(equations) behind this problem.
On the channel 'Discovery Science',a the show-presenter was testing guns.In one of the tests,he fires the gun at a certain distance from a 'BALLISTIC GELATIN'(just a jelly of high viscosity to simulate swine muscle tissue).
The he says,"By using the high-speed camera here,we can tell exactly how far the bullet has traveled through the jelly and hence determine the bullet's velocity and from the cross-section of the bubble inside the jelly,we can determine the impact force of the bullet".
Now,i can't seem to figure out how he can do that!
I can only start off with:
Kinetic energy=work done
,where 'work done=force*penetration depth' is the only thing i can think of.
Thanks!
**I assume there's no other accurate way of calculating the bullet speed,since its almost impossible to measure the velocity of gun recoil to good accuracy*(cons.of momentum)**
