I would really appreciate any help on this. I'm confused with this. 1. The problem statement, all variables and given/known data An empty crate is sliding witha speed of 7m/s over a frictionless surface when it hits a rough patch where .25 is the coefficient of kinetic friction. Find the distance it takes to stop the box. 3. The attempt at a solution Should I calculate acceleration first and if so how do I do the rest of the problem?
