The rolling resistance for steel on steel is quite low; the coefficient of rolling friction is typically μr=0.002. suppose a 180,000 kg locomotive is rolling at 25 m/s on level rails. for the steps and strategies involved in solving a similar problem, you may view a video tutor solution. part a if the engineer disengages the engine, how much time will it take the locomotive to coast to a stop?
