A particle of mass \( 1 \mathrm{~kg} \) is projected upwards with velocity \( 60 \mathrm{~ms}^{-1} \). Another particle of mass \( 2 \mathrm{~kg} \) is just dropped from a certain height. After \( 2 \mathrm{~s} \), match the following.
\begin{tabular}{|l|l|c|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline (A) & Acceleration of CM & (p) & Zero \\
\hline (B) & Velocity of CM & (q) & 10 SI unit \\
\hline (C) & Displacement of CM & (r) & 20 SI unit \\
\hline & & (s) & None \\
\hline
\end{tabular}
(1) \( \mathrm{A} \rightarrow \mathrm{p} ; \mathrm{B} \rightarrow \mathrm{q}, \mathrm{s} ; \mathrm{C} \rightarrow \mathrm{q} \)
(2) \( \mathrm{A} \rightarrow \mathrm{r} ; \mathrm{B} \rightarrow \mathrm{r}, \mathrm{s} ; \mathrm{C} \rightarrow \mathrm{p} \)
(3) \( \mathrm{A} \rightarrow \mathrm{q} ; \mathrm{B} \rightarrow \mathrm{p} ; \mathrm{C} \rightarrow \mathrm{r} \)
(4) None of these
