Question

How much force must be applied to push a 1.35 kg book across the desk at constant speed if the coefficient of sliding friction is 0.30?

Please...someone help me. I am lost as to how to solve this. I would greatly appreciate it if someone could help me out. Thank you much. I promise to give 10 to the best answer.

Answer 1

A constant speed would balance the kinetic frictional force of
1.35*9.81*0.30
=3.97 N
