A delivery company has just unloaded a 500-N crate full of home equipment on the sidewalk in front of your house (Figure). You find that to get it started moving toward your front door, you have to pull with a horizontal force of magnitude 230 N. once it “breaks loose” and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coefficients of static and kinetic friction?
