Question
Example 2: a) A desk has a mass of 68.75 kilograms. If the coefficient of static friction between the desk and the floor is 1.1, what force must be used to move the desk from rest?
b) Once the desk above is in motion, what force must be used to keep it moving at a constant velocity if the coefficient of kinetic friction is 0.73?
b) Once the desk above is in motion, what force must be used to keep it moving at a constant velocity if the coefficient of kinetic friction is 0.73?
