I have a degree in Mathematics and Physics from the Danish University Aarhus, comparable to a masters degree with thesis - majoring in Mathematics. In 1991-92 I was a visting scholar at UCLA, Los Angeles, following graduate courses in Applied Mathematics. Since 1992 I have been a teacher in a high school (gymnasium) in Denmark. Special interests: Applied mathematics, graphics and popularizing Mathematics.

WOW, that is quite spectacular! I am not that familiar with this Maple programming or script syntax. Can you explain? If I remove the three none(), the numbers are moved to the right. 

I am however a bit worried that it will trouble my students in Danish highschool. I wonder if there are more ways to do it, which require less programming? I think Maple should have placed it in the Expression Palette ...

Anyway thanks a lot. I appreciate your reply. Now I know it is possible :)

Thank you so much, Georgios. I appreciate your persistence. Now the colors are fixed! I am not quite comfortable with the Maple syntax here, though. I don't follow the logic here. Now the only missing thing is to make the first finished animation stay alive!!

Thanks Georgios. I could probably automate it with a roundoff command to make it work for other constants too. There is horever a problem: When the animation of the first trajectory finishes it disappears!! I want it to stay visible, when the whole animation has stopped.

Hi again. I don't think it matters if it is version 12 or 13. I observed the same thing like you did. Both curves were red. So somehow the blue color command was overruled ... I don't know if I am on the right track in attacking the problem, or I need to take another approach in order to do what I want. I mean it really makes no sense animating the trajectory if the objects do not move with the right velocity. Then a plain still figure would be more appropriate ... I feel pretty sure Maple can do it, but maybe it needs to be programmed??

Thanks, Georgios. You actually solved another thing that I did not ask for, but still is important for me. I did not know about the view command. So now the only thing which is missing is the animations to develop in the right tempo. The trajectory with air resistance is supposed to finish at t = tslut, whereas the other one is supposed to finish at t = tmax. They do however finish at the same time. I suspect it is because of my choice of frame rate equal to 50. I can't see any way to do it properly ...

NB! Seems like you attached some images too, but they were disabled on my side!

Hi Georgios

I have now uploaded my file after making a few corrections, since I use one of my own packages. Now the worksheet should work for all people. The comments are in Danish, so you probably won't be able to read it :) The code however should be fine. And to your question as to if the plots do work independently: Yes they do, as can be seen in the worksheet.
