Two vehicles are approaching an intersection. One is a 2500-kg pickup traveling at 14.0 m/s from east to west (the negative x-direction), and the other is a 1500-kg Mercedes going from south to north (the positive y-direction at 23.0 m/s). (a) Find the x and y components of the net momentum of this system. (b) What are the magnitude and direction of the net momentum?
