Car A and Car B are traveling in the same direction (call it i^), with B behind A, and initial speeds vA=5.6 m/s, and vB = 6 m/s. The cars have identical mass m=103 kg, and they experience an elastic collision.  Now, this collision is observed by a third person traveling in a car with constant velocity v=6 m/s, traveling in the same direction as the two cars.  From the point of view of this person calculate the following:  The total final kinetic energy as measured from the ground? calculate the total initial kinetic energy. does the third person conclude that the collision is: Group of answer choices elastic inelastic explosive impossible to tell without additional information
