Homework Statement
a fridge with a mass of 120kg is at rest on a kitchen floor. If Ms is 0.32 and Mk is 0.28 and you apply 472N of force what will be the acceleration of the fridge?
m=120kg
Ms=0.32
Mk=0.28
Fa=472N
Homework Equations
Ff=MFn
Fw=mg
Fw=1176N
Fn=1176N
F=ma
The Attempt at a Solution
not sure how to start solving for acceleration. was thinking that i needed to find the net force so that i could plug it into F=ma and solve for acceleration, but i am unsure how to find net force from the given information. could use the Ff=MFn equation but I am not sure whether to plug in static or kinetic friction. any help is appreciated, thank you!
