1. The problem statement, all variables and given/known data 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 m/s. At the same time, car 2 is 1 km east of mile marker 0 traveling at 30 m/s due west. Car 1 is speeding up with an acceleration of magnitude 2.5 m/s^2, and car 2 is slowing down with an acceleration of magnitude 3.2 m/s^2. (a) Write x versus t equations of motion for both cars, taking east as the positive direction. (b) Also, at what time do the cars pass next to one another? 2. Relevant equations xf= xi + vi * t + 1/2 at^2 3. The attempt at a solution x1= (20 m/s) + (1.25 m/s^2) t^2 x2= (1000m) + (-30 m/s) + ( 1.6 m/s^2) t^2 I know this is the right equation for part a. I just need to know the final answer for part b. Thanks.
