Question

A bomb travelling in a parabolic path under the effect of gravity, explodes in mid-air. The centre of mass of fragments will:

• A. Move vertically upwards and then downwards
• B. Move vertically downwards
• C. Move in irregular path
• D. Move in the parabolic path the unexploded bomb would have travelled

Answer 1

The correct option is D Move in the parabolic path the unexploded bomb would have travelled

Since no external force acts on the bomb during explosion, thus the motion of centre of mass of the bomb does not get affected. As the bomb was travelling in the parabolic path just before explosion, so the centre of mass of the fragments will continue to move in the same parabolic path the unexploded would have travelled.
