Problem 274. Bouncing disk
A disk is placed in a rectangular room with dimensions a and b in a point with coordinates x0 and y0. The disk is given a startup speed V, m/s, the angle between the speed and the x axis is phi, rad. All coordinates have metric dimensions. (See the figure below, just right-click on it and choose open in new tab). The friction factor is nu (always greater then zero). The energy loss caused by bumping the walls is negligible.
Find the resulting position of the disk. The answer should be given with the tolerance greater than 10^-3.

could you define "friction factor"?
I meant the coefficient of friction
In that case, what are you using for acceleration due to gravity?
For those wondering, it's 9.80665
Thanks to @bmtran, a bug in testing procedures was resolved.
For those still wondering, the disk is dimensionless.
haha
Can't see image.
