Motion in Cylindrical Coordinates

7:03 what is second component of a(theta)? this -> 2 * r' * (theta)'
I understand everything except that.

See expression for $a_{\theta}$ at time 1:27 in the video.

See equation (4) here.

There is no explanation at 1:27, but link is good.
Thanks !

Can someone find mistake?
Correct answer is 12,66N.I am learning LaTeX !

In the future, a new problem should be posted in a new thread.

I believe the only mistake you made in your solution for the new problem is that your calculator was in degree mode while your angles are expressed in radians.

 

[Vladimir_Kitanov]

I posted it on new thread. Someone merged it.

I will try that.

That would be my fault. I didn't click into the link for his 2nd thread start, thinking it was the same as the original one (which I had locked in a different forum).

Thank you for doing that. It makes it so much easier to read and reply to your calculations when they are in LaTeX. Looking forward to seeing your next thread!

No problem. Thank you.
