A) \[\frac{{{V}_{A}}-{{V}_{B}}}{{{V}_{A}}+{{V}_{B}}}\]
B) \[\frac{{{V}_{A}}+{{V}_{B}}}{{{V}_{A}}-{{V}_{B}}}\]
C) \[\frac{{{V}_{A}}}{{{V}_{B}}}\]
D) 1
Correct Answer: D
Solution :
An elastic collision is one in which both kinetic energy and momentum remain conserved before and after collision. \[{{m}_{1}}{{u}_{1}}={{m}_{2}}{{u}_{2}}={{m}_{1}}{{v}_{1}}+{{m}_{2}}{{v}_{2}}\] Given, \[{{m}_{1}}={{m}_{A}},{{m}_{2}}={{m}_{B}}\]You need to login to perform this action.
