A mass '$$\mathrm{M}$$' moving with velocity '$$\mathrm{V}$$' along $$\mathrm{X}$$-axis collides and sticks to another mass $$2 \mathrm{M}$$ which is moving along $$\mathrm{Y}$$-axis with velocity '$$3 \mathrm{~V}$$'. The velocity of the combination after collision is

$$\frac{V}{3} \hat{i}+2 V \hat{j}$$

$$\frac{V}{2} \hat{i}+V \hat{j}$$

$$\frac{V}{3} \hat{i}-2 V \hat{j}$$

$$\frac{V}{2} \hat{i}-V \hat{j}$$
