A body is projected with velocity $v_{1}$ from the point $A$ as shown in the Fig. $5.114$. At the same time another body is projected vertically upwards from $B$ with velocity $v_{2}$. The point $B$ lies vertically below the highest point, For both the bodies to collide, $\frac{v_{2}}{v_{1}}$ should be a. 2 b. $\sqrt{\frac{3}{2}}$ c. $0.5$ d. 1 .
Two projectiles of mass $m_{1}$ and $m_{2}$ are fired at the same speed but in opposite directions from two launch sites separated by a distance $D$. They both reach the same spot in their highest point and strike there. As a result of the impact they stick together and move as a single body afterwards. Find the place they will land.
Two projectiles $\mathrm{A}$ and $\mathrm{B}$ are projected as shown, (A from origin on ground and $\mathrm{B}$ from height $\mathrm{h}=12 \mathrm{~m}$ above $\mathrm{A}$ ), at the same instant and they meet inmid-air. The relative velocity of $\mathrm{B}$ with respect to $\mathrm{A}\left(\overline{\mathrm{v}}_{\mathrm{z} / \mathrm{A}}\right)$ when they meet is in $\mathrm{m} \mathrm{s}^{-1}$ ) (a) $8 \hat{j}$ (b) $2 \hat{\mathrm{i}}+3 \hat{\mathrm{j}}$ (c) $5 \hat{\mathrm{i}}+3 \hat{\mathrm{j}}$ (d) $-6 \hat{j}$
