Acar moving at constant speed in a straight line with the engine providing a driving force equal to the resistive force f. when the engine is switched off, the car is brought to rest in a distance of 100 m by the resistive force. it may be assumed that f is constant during the deceleration. the process is then repeated for the same car with the same initial speed but with a constant resistive force of 0.800 f. how far will the car travel while decelerating? a. 120 m b. 125 m c. 156 m d. 250 m
