Answer:

[tex]\mu_k=0.5[/tex]

Explanation:

From the question we are told that:

Force [tex]F=75N[/tex]

Weight [tex]W=150N[/tex]

 

Generally the equation for coefficient of friction [tex]\mu_k[/tex] is mathematically given by

[tex]\mu_k=\frac{F}{mg}[/tex]

[tex]\mu_k=\frac{75}{150}[/tex]

[tex]\mu_k=0.5[/tex]
