A) \[\frac{b}{c+b}\]
B) \[\frac{a+b}{c}a\]
C) \[\frac{a}{a+c}a\]
D) \[\frac{a+c}{a}b\]
Correct Answer: C
Solution :
Initial momentum\[=ab\]If \[v\] is final velocity of the combined mass\[(a+b)\],then final momentum\[=(a+b)v\] Equating, we get\[v=\frac{ab}{a+c}\]You need to login to perform this action.
