Impulse / 2-D Collisions / Need Clarification?

[QUOTE="julianwitkowski, post: 4957829, member: 536409"] I know its right because I read it in the textbook, but I wouldn't know what to do if it was a test, and I really want to ace my exam. I guess I just don't really understand about the x and y component of velocity and why the hypotenuse of that right triangle is Δv. What is it the change in velocity because it's not equaling the Δd/Δt of the ball the way I would assume it would? ... Here, this is my problem... My assumption would be Δv = Δd/Δt 32/1 - 0/0.002- -52/1 = /1 which I know is just wrong, but that's the silly thing that comes to mind when I think about this with no external reference. I know this sounds stupid its just, I guess I'm a noob. [I]Thanks for your help though! Very Much Appreciated[/I] [/QUOTE]
