A) \[4\sqrt{2}\,m/s\]at an angle of \[45{}^\circ \] from each body
B) \[24\sqrt{2}\,m/s\] at an angle of \[135{}^\circ \] from each body
C) \[6\sqrt{2}\,m/s\] at \[135{}^\circ \] from each body
D) \[4\sqrt{2}\,m/s\] at \[135{}^\circ \] from each body
Correct Answer: D
Solution :
The momentum of third part will be equal and opposite to the resultant of momentum of rest of the two equal parts. Let v is the velocity of third part. By the conservation of linear momentum, \[3m\times V=m\times 12\sqrt{2}\Rightarrow v=4\sqrt{2}\,m/s\] Hence, the correction option is [d].You need to login to perform this action.
