A red car and a green car, identical except for the color, move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 230 m. If the red car has a constant velocity of 24.0 km/h, the cars pass each other at x = 45.5 m, and if it has a constant velocity of 43.0 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity (in km/h) and (b) the acceleration of the green car?
I know that if xr = 45.5m then xg = 184.5m. And if xr = 76.6m then xg = 153.4m.
I'm not sure what to do with these numbers. Where do I go from here?
