A cannon ball is fired with a velocity of 200ms 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 100m/s and second going vertically downwards with a velocity of 100 `ms^(-1)`. The third fragment will be moving with a velocity of

Options

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

B
