A shell in flight explodes into `n` equal fragments `k` of the fragments reach the ground earlier than the other fragments. The acceleration of their centre of mass subsequently will be

A shell is fixed 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 into two equal fragments. One of the fragments moves along the negative x-direction with a speed of 50 m//s . What is the speed of the other fragment at the time of explosion.

A shell is fired from a cannot with a speed of 100ms^(-1) at an anlge 60^(@) with the horizontal (x-direction). At the highest point of its trajectory the shell explodes into two equal fragments. One of the fragments moves along the negative x-direction with a speed of 50 ms^(-1). What is the speed of the other fragment at the time of explosion ?

At a certain height a shell at rest explodes into two equal fragments one of the fragments receives a horizontal velocity u .The time interval after which the velocity vectors will be inclined at 120^(@) to each other is

An object is project with a speed 10ms^(-1) at an angle of 30^@ with the horizontal. It breaks into n equal fragments during its motion . One fragment strikes the ground at a distance of sqrt(3)m from the point of projection. The centre of mass of the remaining fragments strikes the ground at a distance of 7sqrt(3)m from the point of projection . If all fragments strike the ground at the same time , Find the value of n.

A bomb explodes in air in two equal fragments. If one of the fragments is moving vertically upwards with velocity v_(0) , then the other fragment is moving-

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 shell is fired from the ground at an angle theta with horizontal with a velocity 'v'. At its highest point it breaks into two equal fragments. if one fragment comes back through its initial line of motion with same speed then the speed of the second fragment will be .

A bomb of mass 6kg initially at rest explodes in to three identical fragments On of the fragments moves with a velocity of 10sqrt3 hatim//s another frament moves with a velocity of 10 hatj m//s then the thired fragment moves with velocity of magnitude .
