Answer:
You need to move 105-kg sofa to a different location in the room. It takes a 403-N force to start the sofa moving.
mu = F/N = 403/105×9.8 = 0.4
The coefficient of static friction between the sofa and the carpet will be 0.4

Given:
Wight of sofa = 105 kg
Force= 403 N
Explanation:
weight = mass × acceleration due to gravity 105 × 9.8 = 1029
the mass in given in KG but we work in Newton so to convert it we multiply the mass with 9.8
acceleration = Zero
when it says (constant speed, uniform velocity, maximum velocity)
force = resistance
substitute force with 403 N and resistance with 1029 × μ
403 = 1029 × μ
μ = 1029/403
= 2.553
Answer = 2.553
