A train is traveling with an initial velocity of 20.1 m/sec. If the brakes can apply a maximum acceleration of -0.0500 m/sec^2, how long will it take the train to stop?
---------------
Find the time to stop.
v = at
20.1 = 0.05t
t = 20.1/0.05
t = 402 seconds
---------------
s = 0.5*20.1*402
s = 4040.1 meters
