# Wind foils the plan

A ballistic missile is projected from ground with speed $$100m/s$$ making $$37°$$ with horizontal. After 8 seconds of projection a strong wind starts blowing in the direction of motion imparting an acceleration of $$25m/{ s }^{ 2 }$$. The missile which was to land in enemy's camp is now heading to ally's camp. Find $$\left[ minimum\quad projection\quad speed \right]$$ of the anti-ballistic missile to destroy the ballistic missile if it takes 1 second to deploy it. Assume acceleration imparted by wind to both ballistic missile and anti-ballistic missile is same.

$$g=10m/{s}^{2}$$

$$\cos { 37° } =\frac { 4 }{ 5 }$$
