That is correct.
If you assume the speed along the X axis (horizontal vector) then both are moving 20mph.
If you assume the speed of rotation then the smaller tire would be rotating faster.
I am thinking since the water pressure is uniform the pressure isn't just pushing in 1 direction. Oil is lighter then water thus would exude a tendency to float. Also it is likely warmer then the water it is hitting.
The water pressure at the depth of 5000 ft is found by this formula found here...
What about the notion of keeping the accelerator horizontal with the goal of launching a ship after a certain horizontal velocity is obtained.
There has to be a more sufficient way to launch space-bound ships then burning insane amounts of fossil fuels.
My thinking energy put into...
If time travel to the past was possible then somebody would have done it. Though, it is known to be impossible now but if 20,000 years in the future somebody figures out how to do it, then our current now would already be altered.
Traveling to the future in the sense of faster then 1 second...
In this instance forgo the particle part.
I'm thinking more here like the way a railgun works. Or how some rollacosters can take you from 0 to 60kmph.
Lets say we wanted to make a railgun that uses a large loop to continual increase velocity to a desired point, then release it into an...
