Suppose that while moving into an apartment you move a refrigerator into place by sliding it across the floor. The refrigerator weighs 1452 N and the

Question

coefficient of static friction between the floor and the refrigerator is 0.40. What is the least force you could exert on the refrigerator to move it?

Answer 1

The force must be sufficient to overcome the static friction.

 

F_min = f = μ_sw = (0.40)(1452 N) = 580.8 N
