A) \[v/\sqrt{2}\]
B) \[v/2\]
C) \[v\]
D) \[\sqrt{2v}\]
E) \[2v\]
Correct Answer: D
Solution :
From law of conservation of momentum \[mv-mv\cos \theta =0\] ?. (1) \[mv-mv\sin \theta =0\] ?.(2) From Eqs. (1) and (2), we get \[\theta =45{}^\circ \] \[\therefore \] \[v=\frac{v}{\cos \theta }=v\sqrt{2}\]You need to login to perform this action.
