diagram:

A----------------------> X

angle = 30->

B is traveling at an angle towards the x markso what i have been doing is i have been finding the before and after collision as x and y components. then putting the final xcomponent momentum and y component momentums into this formula :total momentum after = (x^2 + y^2)^.5

i would then have my total momentum before and then the total momentum after with v unknown. i got 4.02 for it. the question is multiple choice and these are the choices 3.23 16.2 2.71 4.02 or 3.76
