A) \[\frac{2v}{\ell }\]
B) \[\frac{v}{\ell }\]
C) \[\frac{3v}{\ell }\]
D) zero
Correct Answer: B
Solution :
[b] Conservation of linear momentum \[{{P}_{i}}=mv-mv=0\] \[\Rightarrow \,\,\,\,\,\,\,\,\,{{V}_{cm}}=0\] Conservation of angular momentum \[\Rightarrow \,\,\,\,\,\,{{L}_{initial}}={{L}_{final}}\] where \[{{L}_{initial}}=\left| \frac{m\ell }{2}v+\frac{m\ell }{2}v \right|=mv\ell \]You need to login to perform this action.
