Try this if you think you can... without cheating!!!The nightmare of nightmare questions :
The Snooker Table of Doom
"oooh... that's just impossible" rating: 9.5/10
A 'snooker' table (measuring 8 metres by 4m) with 4 'pockets' (measuring 0.5m and placed at diagonal slants in all 4 corners) contains 10 balls (each with a diameter of 0.25m) placed at the following coords:
The white ball is then shot at a particular angle from 0 to 360 degrees (0 being north, and going clockwise).
Just to make it clear, a ball is 'potted' if at least half of the ball is in area of the 'pocket'
Assuming the balls travel indefinitely (i.e. no loss of energy via friction, air resistance or collisions), answer the following:
a: What exact angle/s should you choose to ensure that all the balls are potted the quickest?
b: What is the minimum amount of contacts the balls can make with each other before they are all knocked in?
c: Same as b, except that each ball - just before it is knocked in - must not have hit the white ball on its previous contact (must be a red instead of course).
d: What proportion of angles will leave the white ball the last on the table to be potted?
And no - Mr know-it-all'...

And no - Mr know-it-all's imprint on the snooker table is not actually anything to do with the puzzle.
At which point Mr Know-it-all butts in:
OK, fair enough, this one was actually a bit harder than the others - in fact, it took me a whole /hour/ to answer the above four sub-questions
I don’t need a test to know that I most likely could not pass 8 grade math. It’s been too long since I have had to use any of it. Only numbers I need to know are the ones on my paycheck, the ones in my bank account, the ones on the price tags of things I want to buy and the ones listing how many Raves I have.
I also don’t need a stinking test to tell me that I can still kick the poo out of any uppity 8th grader that tries to make me look foolish by spouting out a bunch of mathy stuff. In fact to make myself feel better about all this I think I’m going to head down to my local Jr High right now and smack the crap out of an 8th grader right now! Peace!
i took it anyway to see........lol. i don't remember that kind of math when i was in the 8th grade!! i failed.... .....oh well, after 20 years i still got 5 out of 10 right!!
Congratulations, you got 9/10 correct!
lmao i'm only two years ahead of 8th grade i hope i passed! i really wanna kno wich one i got wrong!!!!!
