Answer:
1.the marble started accerelating the angle didn't change and if you flick the marble it will became fast and the cloth won't affect the marble.
2.the marble collided with the heavy stone the marble going faster after colliding the marble reflected on the other direction left or right not going forward and a bit speed reduction.
3.the marble got a bit of speed of reduction on the heavy stone and reflected not making it go forward making it go left and right and the cloth it didn't do much if the table is very long it might stop.
4.the smaller the object the faster it is the heavier the object how slow it is more mass more gravity the cloth has some friction on it but the marble doesn't it's smooth so it won't affect to it that much
