Physicist Calculates Trajectory of Tiger At SF Zoo 713
KentuckyFC writes "Is it really possible for a 350-pound tiger to leap a 12.5-foot barrier from 33 feet away? (Said another way: a 159-kg tiger, a 3.8 m barrier, and 10 m away.) A physicist at Northeastern University has done the math, a straightforward problem in ballistics, and the answer turns out to be yes (abstract on the physics arXiv). But I guess we already knew that following the death of Carlos Souza at the paws of Tatiana, a Siberian Tiger he had allegedly been taunting at San Francisco zoo at the end of last year."

An object of 750kg can accelerate to 60km/h in 5 impulses (rapid pushes).
How far will an object of 75kg travel when one such impulse is applied at angle of 45 degrees upward?
The 750kg object is a horse. About 5 pushes of hind hooves are enough to reach the full speed.
The 75kg object is a human kicked by the horse (remaining motionless with a counter-push of front hooves).
The result was something like 30 meters. The damage was equivalent to fall from 6th floor.
And they tell us horses can't say "no" when they don't want sex.

If you are going to attack a large predator which both outmasses you and can run much faster than you then you really don't want to use a weapon which will simply annoy it.

What if a child with a limp walks by the tiger enclosure? Or someone with a bandaged wound? Or a stray dog gets into the zoo and barks at the tiger?
What if these jerks had been teasing the tiger on a day when the zoo was full of people instead of a holiday when there was almost no one present?
And actually there WAS a case of a stray dog being attacked by a tiger [google.com] in Tennessee. However that was because the dog (also not big on brains) swam across the moat. Apparently he didn't read the "objects are larger than they appear" sign. Fortunately for the dog, the tiger was young and inexperienced at hunting and keepers were able to distract it and get the dog out. The dog still required surgery for the puncture wounds it received.
I seriously doubt the tiger would have breeched the pen except that it was enraged. This was no prey drive in action--the tiger was not hunting for food (or a limping child). It was just very, VERY pissed off. That doesn't mean the zoo is not responsible, but I would put responsibility at 50-50 between the zoo and the jerks. If one or the other had not been doing the wrong thing, this attack wouldn't have occurred.

It's fascinating that you felt the need to calculate whether or not horses can say no when they don't want sex...

Actually, they use SI [wikipedia.org]. CGS is deprecated, but still appears in lots of older papers, textbooks and the like. Multiple metric systems? The horror!
(Although some would argue that realer physicists just use electronvolts, the speed of light and the Planck constant for everything. Even in situations that don't appreciate it, like tiger attacks. Consider a tiger of mass 8.92*10^37 eV...)

Obviously the tiger evolved, and the zoo budget didn't include studies of the tiger's new superpowers. Same thing happened with the flying squirrel and the electric eel, but in those cases nobody died.
