Your answer is partially correct. Try again. In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xp = 0 and the green car is at xg = 225 m. If the red car has a constant velocity of 25.0 km/h, the cars pass each other at x = 43.4 m. On the other hand, if...
