Example #1 A delivery company has just unloaded a 500-N crate full of home exercise equipment in your driveway. You find that to get it started moving toward your garage, you have pull with a horizontal force of magnitude 230 N. What is the coefficient of static to pull with a horizontal force of magnitude 230 N. What is the coefficient of static friction μ s ? A. - 0.85 B. 1.23 C. 0.46 D. 0.72 E. 0.40

A delivery company has just unloaded a 500-N crate full of home exercise equipment in your driveway. You pull it in order to move it and once it “breaks loose” and starts move, you can keep it moving at constant velocity with only 200 N. What is the to move, you can keep it moving at constant velocity with only 200 N. What is the coefficient of kinetic friction μ k ? A. - 0.85
