What is the relation between the coefficient of static friction, µs, and the coefficient of kinetic friction, µk, for the motion to start?
What is the relation between the coefficient of static friction, µs, and the coefficient of kinetic friction, µk, for the motion to start?
- µs > µk (correct)
- µs < µk
- The relation between µs and µk is not mentioned in the text.
