It is gravity and horizontal free. You have to imagine for example pendulum from old clock. You can call it whatever you want. This pendulum is moving like a hand of a cloack and and the end of it is something like a pipe with water with const velocity. I guess it is non-inertial system because...

What is more i guess we use a non-inertial reference frame because water in pipe is moving relative to the whole pendulum (So there is Coriolis Acceleration). In sum for sure i need to use Coriolis acceleration (Even because lecture was connected with Coriolis Force). So the one that i need to...

Ok then. My teacher said that we have to use Coriolis Acceleration to establish absolute acceleration. What about relative acceleration for these four points? They are perpendicular to their relative velocity? Thanks for help! Regards, Mariusz Kuligowski

And this is proposition with coriolis acceleration. Is it good? http://guzik24x7.twomini.com/third_solution.png

I found some time today to make a little drawing (in paint :D). So I guess i found vectors of centripetal acceleration water (in these 4 points) and whole pendulum. I don't know how will look vector of relative acceleration for these 4 points and vector of Coriolis acceleration. So i...

OK, I will try. I hope that we can do it until friday night. Could You give me some tips? For sure for point one has some centripetal acceleration connected with r? But could You tell me what Vrel? And If I want get Acor i have to use my given data ω and Vrel again. Could you help me establish...

I try everything. I just read some books and it is what I think... I am tired of this pendulum. Coould you please draw these vectors? Because every my solution is wrong. I sent two times to my doctor and i have last one chance. Thanks in advance, Kulig15

The water in pipe has some static V equals V[SIZE="2"]water

Hello guys! This is my second attempt. Can somebody check it? And if it is wrong, can someone try do another one picture? http://guzik24x7.twomini.com/281zjug.jpg Thanks in advance, Regards, Kulig15

Hello and Thanks for the reply. This is a side view. You have to imagine the rotating pendulum with something like a pipe with water. This water has some v and i have to find current absolute acceleration of water in those four points of pipe. Thanks in advance, Kulig

Homework Statement I have to find current absolute acceleration in attached picture in points 1,2,3,4 and draw vectors. The picture is rotating pendulum. The rest data show attached picture: Homework Equations [SIZE="6"]a[SIZE="3"]abs = [SIZE="6"]a[SIZE="3"]rel + [SIZE="6"]a[SIZE="3"]u +...
