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

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
