2.5 Exercise 12

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 $0 . \text{0500 m}/\text{s}^{2}$ ^{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 $0 . \text{550 m}/\text{s}^{2}$, how long will it take to come to a stop from this velocity? (c) How far will it travel in each case?}
