How Long Does It Take for an Accelerating Car to Overtake Another?

[APett]

Say we have two cars, Car A and Car B. Car A is 25 meters ahead and has a constant velocity. Car B has the exact same velocity at this moment, but also has a constant positive acceleration. If I want to calculate how long it takes for Car B to overtake Car A, wouldn't it be the same as calculating how long it takes car B to go 25 meters from standing still? I'm fairly sure it is, but I'm new to physics and afraid there's something I'm missing.

Sorry, I just realized it's probably the wrong subforum. Can someone move it?

You are correct. You are using special relativity (or Galilean relativity). You can translate the problem to the car A reference frame.
