Change in impulse equation

When you calculate impulse do you have to find the individual x and y component?
So for object 2m it can't be:

2m*3-2m*6
right?

yes, find the x and y components of the velocities; momentum is a vector quantity. you talked about impulse...I think you meant momentum...

impulse is change in momentum
