Question
The floor of a railroad flatcar is loaded with loose crates having a coefficient of static friction of 0.48 with the floor. If the train is initially moving at a speed of 52 km/h, in how short a distance can the train be stopped at constant acceleration without causing the crates to slide over the floor?
Solution:

Initial speed of railroad car u = 52 km/h
= 52(5/18) m/s
= 14.44 ...
