Answer. This is due to the newtons's 2nd law of motion. ... While in the case of the stone the monentum is less and the whole glass window comes in motion, thus smashing it.

Answer:
The velocity of stone is much less than that of the bullet fired from a gun. Due to its low speed the stone remains in contact with the window pane for a longer time and hence motion is shared by whole of the window pane.
On the other hand, the bullet fired from gun, remains in contact with the window pane for such a small time that it shares its motion only with a portion of the window pane. That's why it makes a clean hole in the window pane.
