1. The problem statement, all variables and given/known data You are trying to slide a sofa across a horizontal floor. The mass of the sofa is 200 kg, and you need to exert a force of 350 N to make it begin to move. a) Calculate the coefficient of static friction between the floor and sofa b) after it starts moving, the sofa reaches a speed of 2.0m/s after 5.0s. Calculate the coefficient of kinetic friction between the sofa and the floor. Fa= 350N; m=200kg 2. Relevant equations Fnet=ma; Fnet=Fa-Fs; Fnet= Fa-u*m*9.8 3. The attempt at a solution: I tried but i got 35.7 for the static coeffcieint which is why i didn't tried b) please help.
