Statement I: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision.
\( \mathrm{P} \)
Statement II: The principle of conservation of momentum
W holds true for all kinds of collisions.
(1) Statement I is true, statement II is true; statement II is a correct explanation for statement I.
(2) Statement I is true, statement II is true; statement II is not a correct explanation for statement I.
(3) Statement I is false, statement II is true.
(4) Statement I is true, statement II is false.
