Question:
The rolling resistance for steel on steel is quite low; the coefficient of rolling friction is typically \(\mu_{\mathrm{r}}=0.002\). Suppose a \(180,000 \mathrm{~kg}\) locomotive is rolling at \(10 \mathrm{~m} / \mathrm{s}\) (just over \(20 \mathrm{mph}\) ) on level rails. If the engineer disengages the engine, how much time will it take the locomotive to coast to a stop? How far will the locomotive move during this time?
