And how do you find the drag force?

How would you find the drag force? And would you subtract that from the average velocity?

So what I'm trying to prove is that he shouldn't have been able to fly forward for that long in a perfect straight line parallel to the train. I'm thinking of using Δx = 1/2 (vi + vf) Δt to calculate how far he really should've jumped and how he should have fell early on. It's not shown in the...

wait he's only 5'3"?? O.o

oh that makes sense, thank you! :)

yeah of course it can't lol, my assignment is proving why it wouldn't work :p what equations would i use though? i thought drag force would be a factor but I'm not sure how to do the calculations

lol. i mean hypothetically, if this were real...i'm trying to do calculations for a project.

Or is there a way to calculate his speed? I know that since he's technically moving backwards, it's not the same speed as the train. The train's speed is about 300 mph.

Well the whole scene kinda breaks physics in general, but I have to prove why it's unrealistic with equations / calculations.

I think it may have something to do with momentum or vectors, but I'm not sure? Can you explain to me why Wolverine jumping off the train and then flying several feet backwards in a perfect straight line is unrealistic?

I read the article and understand most of it. It's just how they said that they can change the direction the particle moves by changing the laser's polarization. I don't know what polarization is, what does it mean to change the polarization of a laser beam?

http://www.iflscience.com/physics/physicists-develop-reversible-laser-tractor-beam-functional-over-long-distances In this article, they said they could control the particle's direction by changing the laser's polarization. Could someone explain this to me? I have to do a presentation on it...
