Kitty Cannon experiments
Introduction
Object: To find the correlation between cannon angle and distance achieved.
Hypothesis: There are little correlation between angle fired and distance achieved, due to the randomness of the “obstacles”.
There is a game known as kitty cannon on the internet. The object of the game is to basically control the angle of the cannon with the up or down arrow key, then press space bar to fire. There is a red bar that goes in and out which indicates power. When the cannon are fired, the poor helpless kitty is shot out and will encounter the following obstacle:
Spike: The spike impales the kitty and ends the shot.
Venus fly trap: The fly trap eats the kitty, and ends the shot.
Trampoline: The trampoline will bounce the kitty up, however the bounce is exactly like a trampoline, which means the faster the kitty comes in, the faster it bounces out.
TNT: The crate of explosive causes the kitty to fly higher. Incoming angle or speed does not affect the amount of boost, but a kitty with a faster horizontal velocity gets a faster boost, whereas a slow kitty just gets shot up in the sky.
Bomb on a balloon: Has the exact same effect as the TNT, but the balloon hovers at random height. It does not matter if the kitty hits the bomb on the way up or down, the effects are the same (which defies the law of physics).
The premise is to get the highest horizontal distance possible (there are also challenges for the lowest horizontal distance possible). The natural question is, does the angle of the cannon affect the distance obtained in any way, and what angle would give the best chance of getting the 4000+ feet some have claimed to get?
Therefore the purpose of this experiment is to find out what is the best angle to shoot from, assuming maximum power is used.
Experiments
The experiment is conducted on an Acer 5920G laptop, with 2Gig of ram, Intel T7300 CPU, ATI HD 4950 video card with 512 GDDR3, and a 160G SATA hard drive. The game used is found on http://www.addictinggames.com/kittencannon.html .
Ten trials are used, with an interval of 5 degrees, from 10 degree (minimum) to 60 degree (maximum). To ensure constant power, the first result is discarded since there is no way to ensure that the power will be exactly the same for each trial. However the game allows a way of ensuring constant power, by pressing and holding space after each trial, the game will fire the kitty at 90% power. However there is no way to adjust the angle which is why the first result is always discarded.
No kitten or cats are harmed during this experiment.
Result
Conclusion
It would appear that there are little correlation between cannon angle and distance achieved, as it is just a matter of luck. However, the average distance achieved peaks out at around 35 degree, possibly due to the attribute of some of the obstacles. Moreover, it appears that very large distances are possible on any angle, given enough luck. Therefore there are little correlation between maximum distance achieved and angle of the cannon; however it appears that 35 degree gives the best chance of having a high average distance.
