Two cars A and B both at rest took off from a spot simultaneously along the same road towards a town . Car A travelled at 5m * s ^ - 2 and got to the town first with a velocity of 55m * s ^ - 1 If car B got to the town later with a velocity which is two-third of that of car A, (i) calculate the acceleration of car B. (ii) calculate the time interval between the two cars at their arrival​
