Two cars drive on a straight highway. At time t=0, car 1 pass mile marker 0 traveling due east with a speed of 20m/s. At the same time, car 2 is 1km east of mile marker 0 traveling 30m/s west. Car 1 is speeding up with an acceleration of magnitude 2.5m/s, and car 2 is slowing down with an acceleration of magnitude 3.2m/s. (a) write x-versus-t equations of motion for both cars, taking east as the positive direction. (b) at what time do the cars pass next to one another?
