chris556452 Posted February 9, 2010 Share Posted February 9, 2010 I've got a question but dont know the answer... If you had a space ship that could travel at the speed of light, and you turned it down just a notch then shined a flash light straight ahead, would you have a light saber?

JMortensen Posted February 9, 2010 Share Posted February 9, 2010 Let's say you're 200 yards away and want to shoot a falling target, say a brick, where should you aim? Quote Link to comment Share on other sites More sharing options...

JMortensen Posted February 9, 2010 Share Posted February 9, 2010 at or above Im guessing? to accommodate for drop but Id think itd depend on what your firing too Aim right at it. The bullet and the brick are equally affected by gravity. I think that's a tougher question for the person who already shoots a lot, especially skeet. You have to lead a skeet to get the pellets there at the same time that the skeet does, but you don't have to lead a falling object. Quote Link to comment Share on other sites More sharing options...

h4nsm0l3m4n Posted February 9, 2010 Share Posted February 9, 2010 I've got a question but dont know the answer... If you had a space ship that could travel at the speed of light, and you turned it down just a notch then shined a flash light straight ahead, would you have a light saber? Thats an interesting question... I dont think you will "see" anything since your eyes are just seeing light reflecting off objects and into your eye. If you pointed your flashlight at a wall that was moving at very close to the speed of light it would take a long time for the light to travel to the wall and then back to your eye, until that happened you would notice no change. You wouldnt see the light propagating along slightly ahead of you unfortunately. Do we have any astronomers here? Anyone have an idea why this galaxy looks like it has 4 nuclei?

PanzerAce Posted February 9, 2010 Share Posted February 9, 2010 I've got a question but dont know the answer... If you had a space ship that could travel at the speed of light, and you turned it down just a notch then shined a flash light straight ahead, would you have a light saber? If you could get a space ship to c, I'd wonder why you were bothering with a flashlight at all, since you're drive signature would be huge But no, you wouldn't, you would get....a flashlight. Your own perception of light/time/etc wouldn't change, every one else's would. And this thread makes me glad I got a degree in history...though my wallet doesn't like it so much :/ Quote Link to comment Share on other sites More sharing options...
woldson Posted February 9, 2010 Author Share Posted February 9, 2010 I love history, wish I knew more. These are things that just caught my fancy along the way. The things I know the most are, cable tv and sonar on submarines. Quote Link to comment Share on other sites More sharing options...

johnc Posted February 9, 2010 Share Posted February 9, 2010 (edited) Let's say you're 200 yards away and want to shoot a falling target, say a brick, where should you aim? Aim right at it. The bullet and the brick are equally affected by gravity. Well, no... If the brick has is already falling (as implied in your original quesiton) when you shoot, the brick has a head start. If its been falling for about 400 feet then its reached its own terminal velocity. In either case it will be falling faster then the bullet shot out of the gun until the gravity accelerates the bullet to its terminal velocity. Drag also affects the terminal velocity with a brick having a drag coefficient of 2.1 and a bullet in a ballistic trajectory having a drag coefficient of .3. So, I'm will to bet a bunch of money that you're not going to hit the brick if you aim right at it. Edited February 9, 2010 by johnc Quote Link to comment Share on other sites More sharing options...

JMortensen Posted February 9, 2010 Share Posted February 9, 2010 Well, no... You got me. Drop the brick when you take the shot should have been the wording, as far as the drag coefficient, that's why I picked a brick and not a quarter. Don't think it would make enough of a difference to cause a miss. Quote Link to comment Share on other sites More sharing options...
johnc Posted February 9, 2010 Share Posted February 9, 2010 No, you drop the brick when I take the shot. Quote Link to comment Share on other sites More sharing options...

So, I'm will to bet a bunch of money that you're not going to hit the brick if you aim right at it. Also depends on how high the brick was dropped and the height of the gun.. If the gun was 5 ft from the ground and the brick was dropped say 15 ft above the ground, and you shot "upwards" towards the brick...although gravity is affecting the bullet, the bullet is vertically ascending at an angle... so this wouldn't necessarily workout. But say the gun is 5 ft from the ground shooting parallel with a flat surface hoping to intersect the brick at exactly 5 ft above the ground I could see that gravity would affect both objects in that manner Quote Link to comment Share on other sites More sharing options...

That was my next fun fact. When you're shooting level you have to compensate more for bullet drop than if you're shooting up OR down. This time I'll keep my crappy wording out of it. http://www.gamecalls.net/huntingtips/upanddownshooting.html Quote Link to comment Share on other sites More sharing options...
