              \mathrm{\frac{T_1}{2}=\frac{T_2}{2}}
\mathrm{\begin{aligned} T_1 & =T_2 \\ \frac{2 u_1 \sin \theta_1}{g} & =\frac{2 u_2 \sin \theta_2}{g} \\ \frac{\2 u__1 \times \sin 4 5^{\circ}}{g} & =\frac{2 u_2 \sin 60^{\circ}}{g /} \\ \frac{u_1}{v_2} & =\frac{\sin 60^{\circ}}{\sin 45^{\circ}}=\frac{s_3}{2 \times \frac{1}{\sqrt{2}}} \\ & =\sqrt{\frac{3}{2}} \end{aligned}}
