A stone is projected with speed of `50 ms^(-1)` at an angle of `60^(@)` with the horizontal. The speed of the stone at highest point of trajectory is

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 ?
