For a

3\,\text{kg}

block on a horizontal surface the coefficients of friction are

\mu_s = 0.42

and

\mu_k = 0.30

. Answer the following: (a) Calculate the values of

\mu_s N

and

\mu_k N

. (b) When sketching the graph of frictional force

(f)

versus applied force

(F)

, at which two points along the

f

-axis would these values be marked?
