SUMMARY
The discussion focuses on the calculation of train deceleration while traveling uphill, highlighting two primary errors: incorrect math regarding resultant net force and the use of an incorrect equation for calculating distance. Participants emphasized the importance of verifying units and calculations to ensure accuracy. A reference to HyperPhysics was provided as a resource for understanding motion equations.

Would you mind writing down the units (all of them) and see whether they check OK?

I can see two errors:
* Revise your math regarding resultant net force.
* Incorrect equation for calculating distance.
