Two billiard balls are rolling on a flat table. One has the velocity components $V_x=1\mathrm{m}/\mathrm{s}$, ${\mathrm{V}}_{\mathrm{y}}=\sqrt{3}\mathrm{m}/\mathrm{s}$ and the other has components ${\mathrm{V}}_{\mathrm{x}}^1=2\mathrm{m}/\mathrm{s}, V_y^1=2\mathrm{m}/\mathrm{s}$ . If the both balls start moving from the same point if the angle between their paths is $\mathrm{n}\times 5^0$ . Then find $n$.
