Solve the all parts of given question:
Question: The rolling resistance for steel on steel is quite low; the coefficient of rolling friction is typically r=0.002. Suppose an 180,000 kg locomotive is rolling at 21 m/s on level rails.
Part A: If the engineer disengages the engine, how much time will it take the locomotive to coast to a stop?
Part B: How far will the locomotive move during this time?
I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
