...Gly an RC helicopter in a moving bus, will it smack into the back window?

If I fly an RC helicopter in a lift, will it smack into the floor/ceiling?

No, if you don't intentionally fly it straight to the window/floor/ceiling.
Reason: the air you're flying the RC in is inside the bus/lift and moves just as fast as the bus/lift.*

*relative to outside world it's the speed of bus/lift, relative to bus/lift interior it is pretty much stationary.

If someone gave you all the tools to help yourself when you're in a bad situation and you did nothing with them to help yourself do you blame the tools or the person that gave them to you?

That would be the least of your worries. ;)
Depending on which theory you support (no way currently to experimentally verify any such theory that allows matter to travel faster than light in vacuum), you might see the headlights working, at least when you slow back to sub-light velocity, or the causality violation could wipe the humanity from existence (as in Homo Sapiens never became to be a species or was extinct before gaining access to FTL technology), as extreme examples...

Only I would be worthy of blame in this case. It is the responsibility of every person to do what they can to improve their lot in life using whatever resources they have to hand.

I believe that there are two types of problems a person may face. Those they can resolve, and those they cannot. If they resolve the ones they can affect, and pass the ones they cannot resolve to people who can, it should be possible to have a peaceful and stress free life.

As long as both the lift and the bus are travelling in a straight line at constant speed. Should either be subject to any accelerations, things might get "interesting"....

I had a problem with the brakes on my car. The mechanic said he could not fix them, but that he had increased the volume of the horn!

Ah, thanks, that's what I was looking for.
It's a closed system until there is outside influence.
Have I got that right?

Airplane on a treadmill - Variant Thought Experiment


This thought experiment is in a way related to the (in)famous airplane on a treadmill problem.
If you take a ball and place it on a treadmill, will the ball:

  1. Move backwards relative to the ground at the same speed as the treadmill (as if placing any other non-circular object on the treadmill)?
  2. Roll in place without moving relative to the ground (the speed of the treadmill is converted directly into rolling motion of the ball)?
  3. Exhibit some other behavior such as rolling while also moving backwards?
For this problem assume that there is no slippage between the treadmill and the ball (sufficient friction to make full contact at all times), and assume that the ball has mass.
I know the answer is not #1. I am not sure if the answer is #2 or #3. If the answer is #3, what factors affect the movement of the ball? Is it the mass of the ball, the speed or acceleration of the treadmill, and/or other factors?

YES!!!

I got into my Asp, turn on the headlights, and fired up the FSD. Once in Supercruise, I pointed the nose of the ship that way *points*, and pushed the throttle all the way to the stops. After I few beers, I was at 1070C, so I turned on the lights, got the external camera up, and... THEY COULD BE SEEN!!!

For science!

Note:
This would only be true if we had some beers:(

If you drop a cat, it will land on its feet. If you drop a piece of toast, it will land butter-side-down. What happens if you fix a piece of toast butter-side-up on the back of a cat, and drop it?
