Force, constant speed, friction, acceleration
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?
