4. Freight trains can produce only relatively small accelerations and decelerations.
(a) What is the final
velocity of a freight train that accelerates at a rate of 0.0500 m/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 0.550 m/s2 , how long will it take to come to a stop from the initial velocity?
(c) How far will it travel in each case?
