A cannon ball is fired with a velocity of `200 ms^(-1)` at an angle of `60^(@)` with the horizontal. At the heighest point of its flight it explodes into 3 equal fragments. One fragment is going vertically upwards with a velocity of 100 m/s and second going vertically downwards with a velocity of `100 ms^(-1)`. The third fragment will be moving with a velocity of
