Two train cars are coupled together, traveling together on a straight level track with a velocity of 1.50 m/s to the right. The leading Car A has a mass of 5,000 kg, while the trailing Car Bhas a mass of 12,000 kg. (Assume 3 significant figures on all masses.) A small explosion suddenly separates the two cars. Afterward, Car A has a velocity of 2.50 m/s to the right. Ignore all external friction on the train cars. What is the net impulse received by Car A, in kg-m/s? ________ kg-m/s Enter a POSITIVE value for rightward, or NEGATIVE value for leftward.
