**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 ground and velocity of rain wrt man, then we can write

Vr/m = V r/g + Vg/m = V r/g – Vm/g = V r/g + (- Vm/g)

Where (- Vm/g) is the negative vector of Vg/m

I will be adding illustrations soon.
