MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 251 N in the positive x direction to try and move the 59 kg refrigerator. The coefficient of static friction is 0.61. (a) How much static frictional force does the floor exert on the refrigerator? Give both magnitude (in N) and direction. magnitude -352.7 X Considering your Free Body Diagram, how do the forces in each direction compare? N direction negative x (b) What maximum force (in N) do you need to apply before the refrigerator starts to move? N Additional Materials Reading
