Example 5.13 Friction in horizontal motion You want to move a 500-N crate across a level floor. To start the crate moving, you have to pull with a 230-N horizontal force. Once the crate "breaks loose" and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coeffi- cients of static and kinetic friction?

Example 5.13 Friction in horizontal motion
You want to move a 500-N crate across a level floor. To start the
crate moving, you have to pull with a 230-N horizontal force.
Once the crate "breaks loose" and starts to move, you can keep it
moving at constant velocity with only 200 N. What are the coeffi-
