Two particles are simultaneously thrown at an elevation \( 45^{\circ} \), towards each other from points \( A \) and \( B \), roofs of two high
P buildings. Their velocities of projection are \( 14 \mathrm{~m} / \mathrm{s} \) and \( 2 \mathrm{~m} / \mathrm{s} \)

W respectively. Horizontal and vertical separation between points \( A \) and \( B \) is \( 22 \mathrm{~m} \) and \( 9 \mathrm{~m} \) respectively. Caleulate the minimum separation between the particle in the process of their motion.
