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 x = 0 and the green car is at x = 220 m.
If the red car had a constant velocity of 25.0 km/h, the cars would pass each other at x = 44.8 m. On the other hand, if the red car had a constant velocity of 50.0 km/h, they
wouldpass each other at x = 76.5 m. What is (a) the initial velocity of the the green car? Include the signs.
