The discussion centers on understanding how the velocity of rain is perceived by a driver in a moving car, specifically addressing the addition of velocities in this context. Participants explore the relationship between the velocity of rain with respect to the ground and the velocity of the car, considering both vector and scalar interpretations.
Participants do not reach consensus on how to properly interpret the addition of velocities in this scenario, with multiple competing views remaining on the correct approach to the problem.
There are unresolved aspects regarding the assumptions made about the velocities involved and the definitions of terms like "wrt." The discussion reflects differing interpretations of vector addition in the context of relative motion.
Krishna Behera said:Velocity of rain with respect to man is given by the (velocity of rain wrt ground - the velocity of car wrt ground). Here it's not being added up!
I think the "wrt" part is basically saying to only use the horizontal components.No. You need to do vector addition not regular addition.

That is of course true and how my post #3 should be interpreted.CWatters said:You need to do vector addition not regular addition.
