A car of mass 7000kg travelling with a velocity of 100km/hr rams headlong into another car of mass 9000kg travelling at 80km/hr, in which a little boy was playing in the backseat. a). What is the change in momentum of each car, if the cars came to a sudden stop right after impact? b). What happens to the little boy during the impact and why? c). State the laws of motion at work in the scenario described above. d). what advice will you give to the drivers if there is no physical injury on them and why?
