Two paper screens A and B are separated ...

Two paper screens `A` and `B` are separated by a distance of `100m`. A bullet pierces `A` and `B`. The hole in `B` is `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 resistance of paper and air.

Two thin wood screens A and B are separated by 200m a bullet travelling horizontally at speed of 600 m//s hits the screen A penetrates through it and finally emerges out from B making holes in A and B the resistance of air and wood are negligible the difference of heights of the holes in A and B is.

To understand the effect of air resistance on the motion of a bullet let's consider a bullet of the shape shown in the fig. The bullet is flying horizontally. The cross section of cylindrical part is A and the conical part has a semi vertical angle of 45^(@) . Assume that the bullet is fired with initial velocity u and moves in a gaseous medium in which molecules are at rest (do you think this assumption is necessary?). Collisions of the molecules with the bullet are elastic. Take mass of bullet to be M, density of gaseous medium as rho and disregard gravity. (a) Consider two bullets one small and other large, made of same material. Which will experience larger retardation due to air resistance ? (b) Write the speed of bullet after time t (c) Write distance travelled by the bullet in time t.

Points A and C are on the horizontal ground and A and B are in same vertical plane at a distance of 1500 m . Simultaneously bullets are fired from A,Bll and C and they collide at O . The bullets at B is fired at an angle of 30^(@) with horizontal towards the ground iat velocity 100 m//s . the bullet at C is projected vertically upwards at velocity of 100 m//s . the bullet projected from A reaches its maximum height at O . Find the time in which bullets will collide (seconds ):
