A) \[\frac{4u}{238}\]
B) \[\frac{4u}{234}\]
C) \[\frac{4u}{234}\]
D) \[-\frac{4u}{238}\]
Correct Answer: C
Solution :
Here, conservation of linear momentum can be applied \[238\times 0=4\,u+234v\] \[\therefore \,\,\,\nu =-\frac{4}{234}u\] \[\therefore \,\,\,\,speed=\,\,\left| {\vec{\nu }} \right|=\,\,\frac{4}{234}\,u\]You need to login to perform this action.
