1. The problem statement, all variables and given/known data The coefficient of kinetic friction between a refrigerator and the floor is 0.20. The mass of the refrigerator is 100.0 kg, and the coefficient of static friction is 0.25. Determine the acceleration when you apply the minimum force needed to get the refrigerator to move. The answer is 0.49 m/s^2. 2. Relevant equations Sum of the forces: Fx = max = Fa + (-Fs) Fy = 0 = Fn = mg F = ma 3. The attempt at a solution Okay, so I have worked at this problem for quite some time now. I know for a fact that the normal force applied on this object is 980 from solving it through the sum of the forces in the y-component formula. I know that Fs can be written as Us times Fn. If I use static friction, Fs = 245 N. With kinetic, its 196 N. I tried solving for acceleration using either forces (divide F by m) but was not able to get the right answer. Perhaps someone here can assist me? Thanks in advance.
