Answer:

[tex] \: \: \underline{ \boxed{ \large{\sf\mu_s = 0.1}}}[/tex]

Explanation:

The formula to calculate the coefficient of static friction is given by :

[tex] \sf \: \: \mu_s = \dfrac{F}{N} [/tex]

where :

  • [tex] \sf \mu_s [/tex] is coefficient of static friction
  • F is static friction
  • N is normal force

Here we have :

Static friction = 45 N

Normal friction = 450 N

Substitute the required values in the above formula

[tex] \sf\mu_s = \dfrac{45}{450} [/tex]

[tex] \sf\mu_s = 0.1[/tex]

  • Hence, the required coefficient of static friction is 0.1
