* A hundred stones are placed, in a straight line, a yard distant from each other. How many yards must a person walk, who undertakes to pick them up, and place them in a basket stationed one yard from the first stone?

I watch too much of the UK Task Master show on TV... Can you pick up the basket? If you picked up the basket and filled it with stones as you walked along, the distance is a heap less than if you have to walk a yard for the first stone and then walk a yard back to put it in the basket and then two yards forward for the second stone and then two yards back to the basket.

I get into a golf cart, go grab the basket, and then ride along gathering the stones. So, I don't need to walk any steps.

Sum of a series, 0-99, doubled. Instructions easily inferred even if unclear. Solving for Single Rock Capacity Container. First gotcha, stone 1 is 0 yards away. The series is not 1-100, it's 0-99. Each stone is distance X, where X is 0-99, you must walk 2X to retrieve it and return it. 0 + 2 + 4 + 6... + 198 = 9900
IF, however, one begins from the middle. Say, stone number 50 is where the basket resides. Then it becomes the sum of the sums of two series, 49 behind you, and 50 in front of you. This is the minimum distance, starting from the center shaves off the most. 0 + 2 + 4 + 6... + 98 = 2450 2 + 4 + 6 + 8... + 100 = 2550 Total = 5000
As for moving the basket...screw that. You move it. That crap gets heavy FAST.

This fits in the science thread. But I want it to be a riddle for fun.
What is the first manmade object to reach space?
Hint - it will never come back.

Nobody has any ideas?

Nobody has any ideas? With the hint, I'd have to exclude satellites like Sputnik. If I had to guess, probably an early rocket. Maybe even one from Nazi Germany, which would explain why neither the USA nor the USSR made a big deal of it during the space race with all the other "firsts".

The correct answer is "manhole cover" (or rather steel cup). Which also classifies as the fastest man-made object ever. It went 6-times the escape velocity from earth.
This happened 1957 during underground nuclear bomb test detonations. The bomb was detonated in a shaft, which the cuo was covering. Another detail is that it was welded. There is footage of the explosion. The cup is just on one frame.
Note, that there is a debate if this is even true. The scientist that made the first calculations, later got annoyed by the cup being of such an interest to everyone. He then said that he believes that the cover evaporated intead of being launched into space.

I Ah, but the pipe-cup wasn't just the first object in space. It's the first object that stays there and isn't coming back. All rockets fall down (or burn out in the atmosphere). Sobtechnically they aren't first man made object in space, they might have been there, but not anymore. I should have made it clearer, that's for sure. Because reach space doesn't technically mean to necessarily stay there.
