Ah-sweet mystery of life at last I found you!

[Poboy kartman]

Time for a new thread. Post your riddles and puzzles here. From silly to serious, easy to mind boggling, hilarious to droll- whatever.

Here's some to kick it off:

#1- which is heavier a pound of lead or a pound of feathers?
#2- how fast does a bullet drop when fired from a rifle?
#3- which collision has a bigger force of impact on the occupants of a small car: hitting an immovable brick wall at 35 mph, or a head on collision with an 18 wheeler with both vehicles traveling at 35mph?

 

[itsid]

#1 technically identical, but if dropped to your left foot in a bag, the pound of feathers is lighter

#2 it accelerates with 1G to earth (9.81 m/s²) depending on the height of the rifle from the ground ... uhm let's just say it normally hits the ground in less than a second
if the rifle is for example at a height of exactly 9.81m [32 feet 27⁄32"] it's speed is 9.81m/s and it hits the ground in exactly one second

#3 well given the uneven weight of a small car and an 18 wheeler, the latter collision should be almost twice as bad as the first.
Since the truck's inertia is way greater than the car's the car doesn't stand a chance to cancel that out.
if two vehicles are identical though it doesn't matter if one car hits a impenetratable wall or another car going the same speed in opposite direction.

-------------------------

Now me:

2 out of 3 ain't bad.....

I have no idea- Mr. Burns and the dog?

 

[itsid]

what you mean by 2 out of 3?? :toetap05:

oh... okay gun horizontally to the ground! and the vertical speedvector is 9.81m/s of course

'sid

 

[Poboy kartman]

To clarify- #2 was correct, but to put in terms everyone can understand- exactly the same speed as one dropped out of your hand. One thing that did catch my eye was the 27/32 fraction. Where does that come from? I was taught the speed of a falling object was 32' per second per second.

 

[itsid]

I was taught the speed of a falling object was 32' per second per second.

Well yes and no,
The gravitational force is NOT a constant, it 's based on height and earths crust (density) etc.
So, it might be somewhere exactly 32 ft/m² it's most likely not where you are or where I am..
around here we measure in metrics of course, and we use 9.81m/s²
(average value at sea level) and that's 32' 27/32" ..

And if it wasn't my misleading terminology of my answer to your gun question it's 3 out of 3

Ok Sid- 3 out of 3. I was thinking that #3 - the force would be identical, but you're right- they both must have the same mass (I think). I should have stuck to that in my question. I was looking at it as force= mass × velocity but effectively the unyielding mass and velocity of the larger vehicle would effectively shorten the amount of time to go from 32 mph to 0 which for all practical purposes would be the same as increasing velocity.

'sid

No- it was never #2- I just was curious about the 27/32" and kinda figured it came from converting meters to feet. Maybe it's exactly 32' per second and you should get the fraction!

 

[itsid]

Maybe it's exactly 32' per second and you should get the fraction!

No most definitely it's not exactly 32 ft/m²

Sid- Do you realize you posted a puzzle on a trivia thread and just now posted a trivia question on a puzzle thread?

AARRGH- I've seen this before but it's just not coming to me. Thank you very much Adolf Coors......

 

[Half-breeder]

not sure then... here's one for yall to think on...

Which would win in a 'battle' against each other... an immovable object(something that WONT move) VS. an unstoppable force(something that CANT be stopped)... hypothetical ofcourse... seeing as that there are no such things(realistically).

Yeah I was at DACCA when I lost it....

Oh I like this one,
it's easy.. NONE

Yeah I was at DACCA when I lost it....

See, and the most obvious part for being the wrong answer is the "D"
there is no D in any of the following lines... EVER!

But Tihm had the last four correct, everything else was wrong

Isn't this what caused the recent government shut down?

Hmmmm- I'd have to say by definition- neither could prevail. But as a practical matter- I'd have to give the nod to the unstoppable force- because while the immovable object would just sit there and sulk-the unstoppable force could move on and put it all behind him.

Well instead of my explanation I think I'd rather show you one of my favourite yt-channels: minutephysics

.... yea i saw that vid too... but Im one of those guys the dont 'fully' believe things that 'cant' be proven...lol(even on youtube)
