New physics question

MPH is miles per hour, distance over time. The difference between 0 and 100 is 100. The difference between 200 and 100 is still 100. 100 Miles per hour (distance over time) not an abstract physics concept. There is no difference between the two objects in question in terms of distance/time between each other. They also no doubt both have blue/red lights distantly trailing the 200mph car.

Only difference would be the scenery moving for the latter.

And as I'm sure this will be asked next based on your other posts. I'll quote it out so I don't bore everybody, but this is one of the biggest physics issues i've seen firearm owners grapple with:

you failed to mention the skill it takes for me to be a space shuttle door gunner

This dog perfectly demonstrates Foxtrots point:


This also helps with the explanation:



This chick did not do very well with the treadmill question. she forgot her ass doesn't produce that much thrust.




The new physics question:

FoxTrot is all over this stuff... Good job Sir.

Sniper7,... Great pixs! HAHAHA.

What Foxtrot said is the reason I never spent much time thinking about this question. The math shows without a doubt what WILL happen, and from there it becomes a mental exercise of being able to picture it in your minds eye, and convince yourself that the receding vehicle will still appear to recede just as fast, even though now you are moving in the same direction at 50% of its speed, compared to 0% of its speed the first time.

I mean, what Foxtrot already said.


As far as the helicopter one, I thought people were just joking at first. I don't think I know enough about helicopters to get a solid answer on that one. Not to mention I haven't heard any specifics of the scenario. Anyone have more info?

Yes, it will look the same since speed is relative and you are never sitting still anyways.

so if you are driving 65mph and there is a fly in the back of your vehicle, and he flies from there to the front window ...How fast is he going?

Would depend on the direction/rotation of the blades and direction of the turntable relative to the air around it....

A smart fly would use the boundary layer close to the vehicle's skin to fly through, His forward velocity relative to the ground would be in fact greater than 65 mph, but he would not have to over come the direct impingement of the wind while in said boundary layer... Just a thought

You meant inside the car.... shit I am still not a rocket scientist...
