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 the red car is at xr and the green car is at xg m If the red car has a constant velocity of kmh the cars pass each other at x m On the other hand, if the red car has a constant velocity of kmh they pass each other at x m What are a the initial velocity and b the constant acceleration of the green car? Include the signs.
