Hi all, I fell on those pics on the web (see attached files). Now, there are people who tend to think this is a fake, and the others (I would be among them :) ). How to prove it ? I do not know the properties of the porsche windshield (it is a laminated windscreen of course), how much it can withstand but I guess I will be able to find that on the web by myself. Now, let us assume the bird is about 2 kgs, the car 1300kgs. If the bird is at rest and the car is traveling at 200 kph, what would you able to say from that info ? I assumed the collision was...inelastic. Now from what I remember the total momentum is conserved, but that didn't help much, except finding the final speed of the car. Now my guess is I would have to compute the mass of a piece of the windshield same size as the chicken, assuming the chicken remains complete (i.e. is a strong solid) at the time of the collision...and then I determine the force (of that piece of windshield) exerted on the chicken, via the Kinetic Energy. Newton's 3rd law would say the chicken is then applying the same force to the windshield (thus, same work energy on the same distance). Any help :p ?
