A body is projected with a velocity of \( 60 \mathrm{~ms}^{-1} \) at \( 30^{\circ} \)
P
to horizontal.
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline (A) & Initial velocity vector & (P) & \( 60 \sqrt{3} \hat{i}+40 \hat{j} \) \\
\hline (B) & Velocity after 3 s & (Q) & \( 30 \sqrt{3} \hat{i}+10 \hat{j} \) \\
\hline (C) & Displacement after 2 s & (R) & \( 30 \sqrt{3} \hat{i}+30 \hat{j} \) \\
\hline (D) & Velocity after 2 s & (S) & \( 30 \sqrt{3} \hat{i} \) \\
\hline
\end{tabular}

Codes:
\begin{tabular}{lllll}
& A & B & C & D \\
(1) & \( \mathrm{R} \) & \( \mathrm{Q} \) & \( \mathrm{P} \) & \( \mathrm{S} \) \\
(2) & \( \mathrm{R} \) & \( \mathrm{S} \) & \( \mathrm{P} \) & \( \mathrm{Q} \) \\
