i did understand how to get to the final formula, thing is my books are sh*t and i got nothing else to use, using the internet is kind off hard because the font confuses me and we've never done collisions in school, its like I'm trying to relearn everything for eg. i had no idea there was that...

I used the bottom left formula and it helped. Thanks very much, my books did not contain any of these formulas, I've been bashing my head for a long time.

Law of constant impulse (i've learned all this from a book of my native language, sorry for mistranslations) The other equation i know of is m1v1=m2v2 Elastic means that the kinetic energy of both systems is kept throughout the collision

sorry, fixed it, read the guidelines i've tried this, I'm stuck at this atm its why i am here

I am guessing you have to find the speed at which the lighter ball moves and then to use the formula for kinetic energy, which I've tried but I'm not getting it quite right. We got m1=5kg v1=3,5kg m2=2.5kg v2=0 v1prim=? v2prim=? Ek=? How do you get the speed of the lighter ball after collision...
