To get the y component of the resultant vector, add the y components. (These are pointing in opposite directions, though, so we’ll subtract.):

(The result is negative, which means that, because the one that was pointing down was negative, our y component also points down.) Here’s the resultant vector:

Try finding the magnitude and direction of the resultant vector above.

Try this: A car with a mass of 1,000 kg is driving North with a velocity of 30 m/s. Another car is driving at an angle of 45 degrees East of North. It has a mass of 1500 kg and a velocity of 15 m/s. What is the total momentum of this two-car system?
