# Rain and Man problems – How to solve?

Shashank Asked: "How to solve rain and man problems from motion in one dimension?" Answer: The problem is solved using principles of vector addition. There is a simple logic to remember A/C = A/B x B/C If we represent diagrammatically (in the form of vectors) the velocity of rain wrt ground, velocity of man wrt … Continue reading Rain and Man problems – How to solve?
