1. two vehicles collide at a 90 degree intersection. If the momentum of vehicle A is 6.10 x 10^5 kg km/h south and the momentum of vehicle B is 7.20 x 10^5 kg km/h east, what is the magnitude of the resulting momentum of the final mass?
2. two vehicles of equal mass at a 90 degree intersection. If the momentum of vehicle A is 1.20 x 10^5 kg km/h east and the momentum of vehicle is 8.50 x 10^4 kg km/h north, what is the resulting momentum of the final mass?
