Presuming that basic understanding, the shock vectors would be radial to the impact site, so that would push Antarctica to the south, Australia to the east, India to the northeast, EURASIA TO THE NORTH, and the Americas roughly to the northwest and west, if Fischer's shock dynamics is correct.
"and the Americas roughly to the northwest and west"
Call me crazy, but I think Africa should be pushed towards the west just like the Americas, if Fischer's model is to have any internal logical consistency.
If you think otherwise, give me an evidence based argument FOR AFRICA TO REMAIN STATIONARY
Even if we disregard the fact that your analogy is false, considering that in Fischer's scenario you do not have several connected bodies, BUT ONE SUPERCONTINENT your thought example would still be wrong, becausewebolife wrote:Your inelastic projectile fragments have little to do with the elastic collision of an astronomical body with the earth. Little, not nothing; however you should try shooting your projectile at a clump of [roughly] connected bodies and gauge the behavior of the bodies that are peripheral to the impact site as compared to the behavior of the sections close to the impact site.
A PROJECTILE acts completely the same whether the target are connected bodies, disconnected bodies, or a single body.
You want to say that is not the case?
Then show us the video of a impact, where that is not the case, because I can show you right now, dozens of videos where this is the case.
As a matter of record, Africa is pushed up against the southerly section of Eurasia in a bulldozing of several linked ranges, from the Pyrenees to the Caucasus ranges, so yes, as you suggest, Africa was also set in motion. Remember that the earth is a sphere, so don't keep getting confused by the flat map compass directions; follow the shock vectors along great circles.
With regard to the break up of the supercontinent, any model for continental drift presumes the propensity of the primordial continent to fragment along the lines it did. Why those particular plate boundaries is an unknown in any model I've seen to date, including Fischer's. The key point for a simulation experiment is that you'd have to allow for the possibility of the fragmentation in order to analyze the relative motions of the blocks. Which, again, I am surmising you have not tried, so that you can see for yourself what could happen.
