Q1. A man is stationary and he observes that the rain is striking him at 60? from the horizantal. When he starts moving with a velocity of 25 m/s, then he observes that the rain strikes him at an angle of 30? from the horizantal. Calculate actual velocity of rain.

Q2. Rain appear to be falling vertically to an observer who is moving on the road with 6kmph.When he double his speed rain appear to be falling at an angle 30? with vertical . find the velocity of the rain.(Plz If possible solve this without using Calculas or maxima & minima.As i have not yet studied these concept.)
