If the cars are parallel at t0, then the t you want is when their displacement is the same. What is d for a car with v0 and a=2.0ms^-2 ?
A car starts from rest and maintains a uniform acceleration of 2.0 ms^{-2} along a straight road. As the car starts, another car moving in the same direction along a prallel road with a constant velocity of 80 kmh^{-1} passes it. When will the cars be level with each other again?
I know that this is quite a simple question, but no matter what equations attempt to use I can't achieve the correct answer. I tried t = (v-u)/a, letting v = 22.22 ms^{-2}, but got 11.11 s (which is incorrect). Does this mean that Car A was first passed by Car B after 11.11 seconds? Does this have any significance?
Thank you for your patience.
