JEE Main Physics question

Statement 1: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision. Statement 2: Principle of conservation of momentum holds true for all kinds of collisions.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Both statements are true. Since momentum is always conserved (Statement 2), and the two particles have non-zero initial momentum in the same direction, their common final velocity after a completely
