hi
I'm really stuck and I hope you can help me.
I know that linear momentum is a vector, but I'm still not sure how to add them together when :
p1, p2, p ... linear momentum
If two objects A1 ( p1 = 100) and A2 ( p2 = -100) represent an isolated system and are moving along ( parallel to ) x-axis ( A1 in positive and A2 in negative direction ), then total linear momentum p is zero. But what if A1 is still moving along the x axis, but this time function of object A1 is y(x) = 3, while before it was y(x) = 0. Then even though linear momentum vectors p1 and p2 are still parallel, they no longer lie on the same line. Can we still add vectors p1 and p2 as if they were lying on the same line? If yes, why? If not, why not?
thank you
