A shell of mass 2m fired with a speed u at an angle `theta` to the horizontal explodes at the highest point of its trajectory into two fragments of mass m each. If one fragment falls vertically, the distance at which the other fragment falls from the gun is given by :

A

`(u^(2) sin 2 theta)/(g)`

B

`(3u^(2) sin 2 theta)/(2g)`

C

`(2u^(2)sin 2 theta)/(g)`

D

`(3u^(2) sin 2 theta)/(g)`

A projectile of mass mis fired with an initial velocity v_(0) at an angle 0 to the horizontal. At its highest point, it explodes into two fragments of equal mass. One of the fragments falls vertically with zero initial speed. Since the only external force acting on the system is gravitational, the motion of centre of mass of the_ system (the fragments) follows the same parabolic path as the projectile would have followed if there had been no explosion. Force of explosion is internal, it cannot change the trajectory of the system.

A projectile is fired with velocity. v_0 at an angle 60^@ with horizontal . At top of its trajectory it explodes into two fragments of equal mass. If one fragment retraces the path then the speed of the other fragment is

A shell is fired from a cannon with a speed of 100 m//s at an angle 60^(@) with the horizontal (positive x -direction). At the highest point of its trajectory, the shell explodes in to two equal fragments. One of the fragments moves is the speed of the other fragment at the time of explosion.

A projectile of mass 20 kg is fired with a velocity of 400m//s at an angle of 45^(@) with the horizontal .At the highest point of the trajectocy the projectile explodes into two fragments of equal mass,one of which falls vertically downward with zero initial speed, The distance of the point where the other fragment falls from the point offiring is:
