Two thin wood screens A and B are separated by 200m. A bullet travelling horizontally at a speed of 600`ms^(-1)` hits the screen A, penetrates through it and finally emerges out from B making holes in A and B. If the resistance of air and wood arc negligible, the difference of heights of the holes in A and B is

A

B

`49/90` m

C

Two paper screens A and B are separated by a distance of 100 m. A bullet pierces A and then B. The hole in Bis 10 cm below the hole in A. If the bullet is travelling horizontally at the time of hitting the screen A, calculate the velocity of the bullet when it hits the screen A. Neglect the resistance of paper and air.

Two bullets A & B fired simultaneously, horizontally and with different speeds from the same plane. Which bullet will hit the ground first ?
