An 80 N box initially at rest is pulled by a horizontal rope on a horizontal table. The coefficients of kinetic and static friction between the box and the table are 0.25 and 0.5 respectively. What is the friction force on this box if the pull is 25N?
A. 20 N
B. 40 N
C. 25 N
D. 0 N
Answers: 2
= Coefficient of kinetic friction = 0.25
= Coefficient of static friction = 0.5
