Two particles are simultaneously projected in the same vertical plane from the same point with velocities u and v at angles αandβ with horizontal. Find the time that elapses when their velocities are parallel.

A projectile is required to hit a target whose coordinates relative horizontal and vertical axes through the point of projection are (α it is impossible to hit the target if β). If the gun velocity is 2gα ​
