A falling raindrop has a mass of 5.0 x 10^-5kg and is accelerating at a rate of 1.0m/s^2. The drop is acted on by forces of gravity, air resistance, and a crosswind parallel to the ground. (blowing to the left of diagram below). What is the force of wind? What is the force of air resistance? I will attach a pic of diagram in comments.

Please, don't just give me an answer, I want to go into a physics career and really want to learn exactly how to solve a problem like this :)

It is backwards, but you get the point :p

Did you take that picture using a mirror? the words are inverted

anonymous · Answer

I would like to help, is it blowing to the left down?

jellybot23 · Answer

Sorry I am on my computer, so the camera is inverted. The problem is above in the question, the picture is just for showing the diagram. Yes, the wind is blowing to the left

@jayzdd don't leave!! haha

jellybot23 · Answer

Okay, looks good :)

jellybot23 · Answer

Now how do we apply equations and such?

anonymous · Answer

do you agree that angle is 30 degrees, between wind vector and weight vector

anonymous · Answer

by the way, you can take a screenshot with this program https://app.prntscr.com/en/index.html

jellybot23 · Answer

Thank you! And yes, I agree on the angle

anonymous · Answer

by newtons 2nd law
$ \sum $ F = m*a

jellybot23 · Answer

Yes, so do we do 1.0 X 10^-5 times 1.0 m/s^2?

anonymous · Answer

component wise newtons second law is 
∑Fx = m*ax
∑Fy = m*ay

jellybot23 · Answer

Okay, agreed

jellybot23 · Answer

Okay, sorry about it being backwards, I can take a pic on my phone and re-upload it if you would like

jellybot23 · Answer

Okay, one minute!

jellybot23 · Answer

My computer isn't cooperating, I am getting there

anonymous · Answer

much better

jellybot23 · Answer

Haha YAY!

anonymous · Answer

it looks like the rain drop is moving at 30 degrees west of south, and thus the acceleration is also in that direction. by newtons law the net force vector has the same direction as the acceleration

jellybot23 · Answer

Okay agreed
