Question

Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 19.0m/s . At the same time, car 2 is 0.90km east of mile marker 0 traveling at 29.0m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.20m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.60m/s2
At what time do the cars pass next to one another?

Answer 1

The solution would be a lot easier from the frame of reference of either car.
