A cannon ball is fired with a velocity 200m / sec at an angle of 60° with the horizontal. At the highest point of its flight it explodes into 3 equal fragments, one going vertically upwards with a velocity 100 m / sec , the second one falling vertically downwards with a velocity 100 m / sec . The third fragment will be moving with a velocity

C. `300 ms^(-1)` in the direction making `60^(@)` with the horizontal
D. `200 ms^(-1)` in the direction making `60^(@)` with the horizontal

Answer
