The answer is B, and the solutions manual says that the horizontal momentum of the two masses is 0 but I don't understand why. Anyone care to explain why that's the case and we only use vertical momentum of the 10 kg mass and no horizontal momentums

Cos 60 x 10 = 5 x Cos 1 Then you use m1v1 = (m1+m2)v2 for ineleastic collision using the vertical velocity, solve for v2 and it ends up being B. Upvote 0 Downvote

I try to do calculations like that in my head but I guess I just slipped up. Thanks a lot! Upvote 0 Downvote
