You have been perplexing to slip a fridge opposite a plane floor. The mass of a fridge is 194 kg, as well as we need to strive a force of 349 N to have it only proceed to move.
After it starts moving, a fridge reaches a speed of 1.7 m/s after 4.9 s. What is a fellow of kinetic attrition in between a fridge as well as a floor?
Thanks for your help

Acceleration is 1.7 / 4.9 = 0.347 m/s/s
F = matriarch = 194 . 0.347 = 67.3 N
That is a force indispensable to supply a acceleration. The "left over" force contingency be used to strike a attrition force.
Friction force = Total force – accelerating force = 349 – 67.3 = 281.9
Friction force = µ(k) . N
281.9 = µ(k) . 194 . 9.8
µ(k) = 0.15
