Gravity experiment (Posted on 2006-05-04) Difficulty: 3 of 5
You are studying the effects of gravity on clay spheres. You conjecture that they will shatter... but at what height? You want to find out the smallest integral height in meters from which the clay will fall and shatter.

Unfortunately, you only have four identical clay spheres, at least until the company that makes them starts returning your calls. Also, you only have enough time for 8 tests, during which the general area will be cleared of people. Last time someone did such an experiment, an egg... well, it was messy. Up to what height can you test the effects of gravity on the clay?

Hints/Tips re: That's the breaks (Possible correct solution) | Comment 8 of 29 |
(In reply to That's the breaks (Possible correct solution) by Dej Mar)

So wait, if you drop the first sphere at 92 meters and it breaks, what do you do if the second sphere never breaks?  All you will know is that the break point is somewhere between 63 and 92 meters...
