I think this might be a really simple question, but i'm not sure.
A car driving at a speed of 80km/h is going to rear-end a car moving at a speed of 60km/h. What is the maximum speed the first car can have just as it reaches the second car, to avoid a collision?
I think the answer is just 60km/h, but that's just my logical thinking. I don't think any of the equations for constant acceleration apply here, since I'm only given 2 velocities.

I am a basement physicist so it might just be jiberish. I hope this makes sense. lol
Hey it's just a thought, at least it is original!


"Think of the universe as a hologram, depth is an illusion but we experience it because we are in the hologram.

ok, then imagine our universe as a sheet of paper( the hologram) floating in space.
This represents a brane.

There would be the dimensions we "feel" on the hologram but there would also be extra dimensions outside of the brane right?

But if we were on the outside in space and the branes were very small, there would be extra dimensions within the brane that we couldn't see nor feel unless we could enter the brane (hologram).

The brane can thus "feel" the dimensions of itself and the dimensions outside of itself."

By falling through, I mean uninjured of coarse. The world record for unassisted sky diving speed is recorded at 614 mph (http://en.wikipedia.org/wiki/Freefall#With_air_drag)
The Bell 206 has a Rotor diameter of 33 ft 4 in (10.16 m) but I'm not sure what the minimum rotor speed to hover is.

The alkali metals (group 1) tend to form 1+ ions while alkali earth metals (group 2) tend to form 2+ ions because:
a. alkali metals are less massive
b. this is a random occurence
c. the changes of these ions corresponds to the number of valence electrons that may be lost
d. the ion an atom forms is always equal to the group number

only answer if you know for sure

Ohms Law states that
1 ohm = 1V/1A
(V= volt, A=ampere)
But in superconductivity, resistance is zero. But then, how can V be zero, if current is passed through a superconductor? Whatever other numbers V and A are made, the division cannot be equal to zero. Then, are superconductors an exception to ohm's law?
