Question

A bullet fired from a gun makes a small hole in the window pane while passing through it,but the stone striking the window pane breaks it into pieces. Why ?

Answer 1

because firstly the bullet is of small size and contains greater quantity of motion net then off stone so because of Greater velocity it passes and make hole and as time taken is less so it does not cause much destruction in the window but stone is moving with very less velocity and large surface area so it takes very much time and just much Destruction as compared to bullet.
I hope that it was helpful

Answer 2

Explanation: 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.
