As per your syllabus, the coefficients of static and kinetic friction satisfy which order?
Aμ_s = μ_k
Bμ_k > μ_s
Cμ_s = 0 always
Dμ_s > μ_k
Answer & Solution
Correct answer: D. μ_s > μ_k
Your syllabus: experimentally μ_k < μ_s.
That is why a force just sufficient to set a body moving keeps it moving with acceleration.
