If a train traveling at 30 m/s brakes to a stop in 1 minute, what is it's acceleration?
------------------
Its (no apostrophe) acceleration is
(30 m/s)/60 sec = 0.5 m/sec/sec or m/sec^2

For this problem the initial speed is 30 m/s, and the final speed is 0. Since the speed is expressed in meters per second, the time must be expressed in seconds. One minute = 60 seconds, so:
\left(60\ \text{seconds}\right))
Solve for 
, remember to pay attention to your units of measure, and check your answer for reasonability.
