In this task I need using the given equations of motion of point M, determine the shape of its trajectory and, for time t = t1 (c), find the position of the point on the trajectory, its speed, the full, tangent, and normal acceleration, as well as the radius of curvature of the trajectory at the corresponding point.

And I don’t know if the task is done correctly under the given conditions

@Kitonum 

Could you check is it right calculations and plot? I did it a few days ago, but I think that is wrong

@Kitonum 

Thank you very much

@Kitonum 

Thank you very much

@Carl Love 

Yeah, I know Maple not so good and don't know how integrate etc. And need all calculations are those made in Maple

@tomleslie 

Perfect thank u so much

@tomleslie 

Hi, yes thank u

Could you add another cylinder to the code with the same parameters as a 2 moving cylinder?

 

@Preben Alsholm

Thank u so much, very much helped :D
