A) \[m\]
B) \[2\,\,m\]
C) \[3\,\,m\]
D) \[\frac{3}{2}m\]
Correct Answer: C
Solution :
Key Idea: In elastic collision kinetic energy and momentum are conserved. Let \[{{u}_{1}}\] be the initial velocity of a particle before collision and \[{{v}_{1}}\] the final velocity after collision, then change in kinetic energy is given byYou need to login to perform this action.
