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 = 220 m. If the red car has a constant velocity of 20 km/h, the
cars pass each other at x = 44.5 m, and if it has a constant velocity of
40 km/h, they pass each other at x = 76.6 m. What are (a) the initial
velocity and (b) the constant acceleration of the green car?
