Freight trains can produce only relatively small accelerations. (a) what is the final velocity of a freight train that accelerates at a rate of 0.0500m/s2 for 8.00 min, starting with an initial velocity of 4.00 m/s? (b) if the train can slow down at a rate of 0.550m/s2, how long will it take to come to a stop from this velocity? (c) how far will it travel in each case?
