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 20.0 m>s. At the
same time, car 2 is 1.0 km east of mile marker 0 traveling at 30.0 m>s
due west. Car 1 is speeding up with an acceleration of magnitude
2.5 m>s2
, and car 2 is slowing down with an acceleration of magnitude 3.2 m>s2
. (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?
