Freight trains can produce only relatively smallaccelerations and decelerations. (a) What is the final velocityof a freight train that accelerates at a rate of 0.0500 m/s2for 8.00 min, starting with an initial velocity of 4.00 m/s? (b) Ifthe train can slow down at a rate of 0.550 m/s2, how longwill it take to come to a stop from this velocity? (c) How far willit travel in each case?

Question

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 this velocity? (c) How far will
it travel in each case?
