A) v/2
B) 2v
C) \[v/\sqrt{2}\]
D) v
Correct Answer: C
Solution :
Initial momentum of the system \[{{\vec{P}}_{i}}=mv\hat{i}+mv\hat{j}\] \[|{{\vec{P}}_{i}}|\ =\ \sqrt{2}mv\] Final momentum of the system = 2mV By the law of conservation of momentum \[\sqrt{2}mv=2mV\Rightarrow V=\frac{v}{\sqrt{2}}\]You need to login to perform this action.
