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 15 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 want help to find how much time will it take the locomotive to coast to a stop.
