The total momentum of two cars approching an intersection is Ptotal = (15,000 kg.m/s)x + (2700 kg.m/s)y. (a) If the momentum of car 1 is P1= (11,000 kg.m/s)x + (-370 kg.m/s)y, what is the momentum of car 2? (b) Does your answer to part (a) depend on which car is closer to the intersection? Explain.
