हिन्दीGiven below are two statements regarding collisions: Statement I: In a completely inelastic collision in one dimension, the colliding bodies stick together and move with a common final velocity. Statement II: In any collision, the total mechanical energy is always conserved without any conversion to thermal energy or sound. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
Statement I is correct by definition of completely inelastic collision. Statement II is incorrect because in inelastic collisions, part of initial kinetic energy is converted into heat and sound.
