I am not familiar with calculus in polar coordinates but i want to try. What does that dot on top mean, is it first degree diffrentiation, like f'(x)?

Thanks for the confusion. Seriously, which ans is more accurate? I used $$\theta=arc/radius$$

I have tried fixing that latex mistake But i can't find it. I have written it out and posted in #15, this time a bit more clearer. Using that $$d\theta=vdt/l$$ $$d\theta/dt=v/l$$ Thanks, I will verify the answer tommorow from our teacher

So a will be really small, making an angle slightly less than 90, to not change the magnitude Exact angle would require the angle between ## \vec V ## and ##\vec V'## Of course this is for vector addition of V and a*t, but i could draw no other conclusions from this

Here is the working so far

I have drawn it multiple times, I am not trying to solve the problem in my head. Even the book has a detailed picture Here is one I found on the web, just to show that i know what you are saying http://2.bp.blogspot.com/-lLb0RcwG_LQ/UKpPDbIYQ-I/AAAAAAAAB3s/Yklf-9iXLQ8/s1600/scan00014.jpg Please...

I assume that for dt time they don't change their direction and move in straight line. $$\text{Initial slope}=\sqrt{3}$$ $$\text{Slope after }dt=m _2$$ $$d\theta= \tan^{-1} \left(\frac {l*\frac sqrt{3} 2 -dl \sqrt{3}} {\frac l 2}}-sqrt{3}\right)$$ It is V^2/r, but i will need radius of...

I made another attempt at it. I assumed that the triangle that forms between the three, rotates with a constant angular velocity. This too yielded nothing. This is the working for that https://m.imgur.com/gallery/9X34cs1

I have tried assuming that they move dl distance along the stright line in dt time, ignoring the direction change. Then I used co-ordinate geometry to find the new slope and calculate d(theta). I was left with a value that had terms of dl and dt, and hence useless

Yes the magnitude of their velocity remains constant but the direction changes, like in uniform circular motion
