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 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 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 ?
