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

Options

  1. Aboth parts continue to move in the same direction as that of the original body
  2. Bone part comes to rest and the other moves in the same direction as that of the original body
  3. Cone part comes to rest and the other moves in the direction opposite to that of the original body
  4. Done part moves in the same direction and the other in the direction opposite to 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

Step-by-step solution
