Motion Equations for Constant Acceleration in One Dimension (Problem 29)

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 $0.{\text{0500 m/s}}^2$ no-selfclose 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 $0.{\text{550 m/s}}^2$, how long will it take to come to a stop from this velocity? (c) How far will it travel in each case? Select the answer to part (a).
