If you fired a bullet in a desert...

id stand in front of the second bullet, coz it wont even come close to me. the wind would probably change its direction anyway.

a 44 magnum bullet will travel just under 1.5 miles, and it's not the same as shooting a round horizontally as it is vertically. A bullet shot in the air will reach it's apogee whereas a horizontally shot rounds bullet will lose speed naturally rather than because of the air pressure and the slight change in gravitational pull
 
What if you are in the antartic as aposed the a desert......

Would that make a difference?

Like, would the bullet freeze in mid air when it runs out of steam and remain there for all eternity.........
 
Here's one I was asked at an interview:

Consider a hypothetical situation where a hole is drilled, from the North Pole, right through the centre of the Earth to the South Pole, along the Earth's axis of rotation.

A small sphere is then dropped into the hole, describe it's motion in terms of conservation of energy and simple harmonic motion and say what happens when it's kinetic energy has fully dissipated.

Now, consider if we moved the hole, so instead of it being along the axis of rotation we put it say... on the equator, going through the centre of the Earth again and to another point on the equator. How will the Earth's rotation effect the sphere on this occasion?

Now, say we had a step ladder and decided to drop the sphere from the top of the step ladder, how would this effect the motion?

And finally, what if we dropped the ball from thousands of feet in the air, what would happen if we dropped it from directly above the hole? How could we be more shrewd with our choice of drop point in order to achieve a better result?


The worst hour of my life...

Horrifying for a (then) 16 year old.

But as there seems to be some interest in dynamical systems on here I thought I'd give the bored people something to do!

I would simply counter that by asking 'how do they get the jam in the middle of donuts?' that'll have the feckers confused ;-)

I recently shot a .22 bullet ( not a pellet, one from a live firearm rifle) at a rabbit and missed. If anyone finds it, PM me.
i saw a rabbit that didnt have a bullet-hole in it,i wonder if......

pretty sure they use an oompah loompah for that.

The bullet will take about 1hr 20min to hit him in the back of the neck, assuming the earths circumference is 24,000 miles, the exact time will depend on the exact circumference of the earth at that point.
