1. Information I have:

v=??
d=0.4 km
t=0.75 s
average acceleration= -.1 km/s2


Homework Equations



Need to find out what is the maximum speed that car will not reach displacement (acceleration doesn't change)



The Attempt at a Solution



final velocity= starting velocity + acceleration x time

For a PHYSICS problem the numbers are not the main thing.
If you don't explain what actually happens in the problem the numbers are meaningless.
It will help you too to try first to UNDERSTAND what is going on and then look at the numbers.
So don't dismiss the "story" in a problem, this is the main part...

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
