Obtaining the absolute velocity of a moving train based on angle of raindrops with respect to vertical axis
The problem is in the files attached.
I have been given the coordinates of the raindrops both start and end.
My question is how do I obtain the angle, and after that how do I arrange the equation to get Vtrain.
Answer
- The questioner was satisfied and accepted the answer, or
- The answer was disputed, but the judge evaluated it as 100% correct.

Thank you Philip, is ThetaWind always 30 degrees? I still dont quite get how to obtain the angle from the coordinates I was given. However everything you explained makes sense now.
-
In general ThetaWind may not be 30 degrees, but in your problem it is assumed to be 30 degrees.
-
Oh okay, so if I understand the assignment the first step in finding Vtrain should be to find the angle of the raindrop vectors using the coordinates that I was given? Should I do that using the slope?
-
Yes.
-
Great, thank you for the help Philip :),
-
Sorry for asking again Philip, but how would I obtain Vtrain with respect to a fixed refrence, so the absolute velocity of the train?
