i got a request from teacher
[quote]2. The trajectory mapped out for h<2.5r assumes that the track is imaginary. For a real track, it won't be like this, i.e. the object will be confined within the loop. Is it possible to simulate the real case?[/quote]
i not sure how to handle the collision condition elegantly.
do you have the time to code this inside your model so i can study your idea?
can add codes into your model that after free fall hits track and move in circular motion (assume e=0) to move off with velocity tangential to the circular track?
my latest version is here
