If a #1 kg# object moving at #1 m/s# slows down to a halt after moving #1 m#, what is the friction coefficient of the surface that the object was moving over?
The coefficient of friction is
The coefficient of kinetic friction is
The normal force is
Initial velocity is
Final velocity is
We apply the equation of motion
The negative sign indicates that it is a deceleration.
According to Newton's Second Law,
