Two particles $$\(P\)$$ and $$\(Q\)$$, of masses $$\(0.2 \mathrm{~kg}\)$$ and $$\(0.5 \mathrm{~kg}\)$$ respectively, are at rest on a smooth horizontal plane. $$\(P\)$$ is projected towards $$\(Q\)$$ with speed $$\(2 \mathrm{~m} \mathrm{~s}^{-1}\)$$. Write down the momentum of $$\(P\)$$. ........................................................................................................................................................ ........................................................................................................................................................ ........................................................................................................................................................ ........................................................................................................................................................
