A "rocket car" is launched along a long straight track at t=0s. It moves with constant acceleration a1=1.2m/s2. At t=2s a second car is launched with constant acceleration a2=7.2m/s2.(adsbygoogle = window.adsbygoogle || []).push({});

At what time does the second car catch up with the first?

How far down the track do they meet?

I always have problems with these problems because you need to use the kinematics equations and i get confused. Any help would be greatly appreciated.
