Two paper screens A and B are separated by a distance of 100m. A bullet pierces A and then B. The hole in B is 10cm 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.

1.	Two paper screens A and B are separated by a distance of 100m. A bullet pierces A and then B. The hole in B is 10cm 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.
Answer» Solution :The SITUATION is SHOWN in Fig. `d = usqrt((2(h_(1)-h_(2)))/(G))` `100=usqrt((2xx0.1)/(9.8))` u = 700m/s
