Question

A projectile is fired from a point with velocity $\mathrm{v}_{1}$ making an angle $30^{\circ}$. AT the same time another body is fired vertically upwards from a point just below the highest point reached by the first with velocity $v_{2}$. The ratio $v_{2}$ to $v_{1}$ for the bodies to collide will be\

Professor PC Thomas Classes · Answer

If they collide, the condition is\ Time taken by (1) to reach $\mathrm{A}=$ Time taken by (2) to reach A\ $\frac{v_{1} \sin 	heta}{g}=\frac{v^{2}}{g}$\ $\frac{\mathrm{v}_{2}}{\mathrm{v}_{1}}=\sin 	heta=$
