A cannon ball is fired with a velocity $200\, m/sec$ at an angle of $60^o$ 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

  • A

    $100\, m/s$ in the horizontal direction

  • B

    $300\, m/s$ in the horizontal direction

  • C

    $300\, m/s$ in a direction making an angle of $60^o$ with the horizontal

  • D

    $200\, m/s$ in a direction making an angle of $60^o$ with the horizontal
