Answer:
Force is needed to begin to move the book and force needed to keep the book moving at a constant velocity is 10.78 N and 5.85 N.
Explanation:
Given :
Mass of book , M = 2.03 kg.
Coefficient of static friction ,
Coefficient of kinetic friction ,
Force, required needed to begin to move the book ,
Now, We know kinetic friction acts when object is in motion .
Therefore , Force, required o keep the book moving at a constant velocity
Hence, this is the required solution.
