a driver of a car travelling at `52 km//h` applies the brakes and acceleration uniformly in the opposite direction. The car stops in `5 s`. Another driver going at `34 km//h` in another car applies his brakes slowly and stops in `10 s`. On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied ?
