SUMMARY

The discussion centers on calculating the stopping distance of an empty crate sliding at 7 m/s on a frictionless surface that transitions to a rough patch with a coefficient of kinetic friction of 0.25. The key to solving this problem involves determining the acceleration due to friction and applying energy methods to find the distance required for the crate to come to a complete stop. The solution requires the use of Newton's second law and the work-energy principle to derive the stopping distance accurately.

I would really appreciate any help on this. I'm confused with this.

Homework Statement


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.

The Attempt at a Solution


Should I calculate acceleration first and if so how do I do the rest of the problem?
