It's a good way to find a person who'll believe whatever you tell them because they want to impress you. You use that tactic, you always end up finding "the heaviest ball" even if they're all the same. Good recruitment tactic for finding a clever patsy/fall guy.

Split the balls into two sets of 4. Whichever is heaviest contains the large ball. Then split the four with the heaviest ball into two groups of two. Find the group with the heaviest again. Split that into two, and bam, you have the heaviest ball. They asked us something similar when I was at a place. Dumbass questions ITT

Clearly you should just roll the balls down a ramp and see which one accelerates the fastest.

GBS used to be smart enough for threads with puzzles like this but I dunno if we're at that level any more. Here's my entry, you can work for me if you answer this. (.....NOT!!) You are sharing a pepperoni pizza with your fellow goon. It has a lot of pepperonis on it, but cleverly, you notice that some of the slices have more pepperoni than others. Obviously you want to try to maximize your pepperoni count, that's some basic goon instinct there. The way you go about choosing slices is, you go first, and take any slice you want. Then, the other guy takes one of the two slices adjacent to the first one. This continues to alternate, so each of you has two choices for each slice. Is there a way you can guarantee that you get more delicious pepperonis than the other goon?

Moridin920 posted:if all the balls are the same size and shape though wouldn't it not matter? air resistance would be the same for all of them If they are the same shape and size and one is heavier (re more dense) then it will better overcome an equal amount of air resistance and accelerate faster. It should also have a higher terminal velocity. I think rolling them down a ramp would be easier to observe than dropping them tho.

Moridin920 posted:if all the balls are the same size and shape though wouldn't it not matter? air resistance would be the same for all of them Gravity is proportional to an object's mass, so all objects will accelerate at the same rate under gravity in a vacuum. Air resistance is a force that is proportional to velocity, but not to mass. The heavier an object is, the smaller effect that same amount of force will have, so heavy things will fall faster because the same air resistance will have less of an effect. trap sprung or something

No one said anything about incline planes. The instructions were 8 balls and a scale.

Wait guys, actually I have a better idea. You can just heat all the balls in a fire for 10 minutes.Then you touch each one. The heavier ball will be slightly cooler.

If you can juggle you could probably get a feel for which ball was not like the others by doing so.

ArbitraryC posted:what if it's one of those places that cuts their pizzas into square slices I don't know I would never eat one of those!! That would change the problem a lot actually because now you have four adjacent pieces to any piece and taking a piece could enable one to choose between 0 and 3 other slices, inclusive. I'm not prepared to answer such a question.

Here's a fun one I heard on the radio recently: You have 100 coins weighing 10 grams each, in 10 stacks. One stack is fake coins, and they all weigh 11 or 9 grams. You have an accurate scale. How do you find the fake coins with only one measurement?

notZaar posted:Here's a fun one I heard on the radio recently: I'm guessing the solution is something like you use 1 coin from stack 1, 2 from stack 2, and so on, and then based on how far off you are from that target total you know which stack was fake, ie if you're 5 grams off the stack you used 5 coins from is fake.

put all the balls at the edge of a cliff. push all the balls off until you have only one left. that is now the heaviest ball

# ? Jul 17, 2015 20:46 |

surely just only weigh two balls at once until you find the one which is heavier?

Moridin920 posted:oh that makes sense basically just imagine force vectors, F=ma and all. a here is constant (gravity) so the larger the m the more downward force you're applying. The resistive force is going to be the same for an object of the same/shape size traveling the same velocity regardless of mass, so when you balance your force vectors the heavier ball (assuming same size and shape) will have more net force downwards, resulting in greater acceleration.

Yeah pretty much. You can stop at the ninth stack.

That's the trick to most these riddles, when you look at what you're given it becomes clear what you're supposed to do. If the solution didn't involve using varying amounts of coins why wouldn't they just say you had 10 coins and 1 is fake.
