A free body of mass $8 \mathrm{~kg}$ is moving at $2 \mathrm{~m} \cdot \mathrm{s}^{-1}$ along a straight line. It splits into two equal parts due to an internal explosion releasing $16 \mathrm{~J}$ of energy, and neither part deviates from the original line of motion. Finally,

• A

  both parts continue to move in the same direction as that of the original body
• Correct answer
  B

  one part comes to rest and the other moves in the same direction as that of the original body
• C

  one part comes to rest and the other moves in the direction opposite to that of the original body
• D

  one part moves in the same direction and the other in the direction opposite to that of the original body

Hence, the correct answer is option: 'B'.
