Two cars, A and B, are travelling in the same direction, although car A is 183m behind car B. The speed of A is 25.3 m/s, and the speed of B is 19.4 m/s. (a) How much time does it take for A to catch B? (b) If at the end of this time, A begins to decelerate at 2.5 m/s2, calculate the total distance travelled by A.
