Complete Question
A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.
Answer:
The value for static friction is
The value for static friction is
Explanation:
From the question we are told that
The mass of the clock is
The first horizontal force is
The second horizontal force is
Generally the static frictional force is equal to the first horizontal force
So
=>
=>
Generally the kinetic frictional force is equal to the second horizontal force
So
