Answer:
the minimum coefficient of static friction is [tex]\mu_s = 0.63[/tex]
Explanation:
From the Question we are given that
The force of static friction(i.e the net force ) is [tex]F_s = 467.88N[/tex]
The normal force is [tex]N = mg[/tex]
where m is the mass = 76 Kg and
g is the acceleration due to gravity
Now the minimum coefficient of static is friction is mathematically represented as
[tex]\mu_s = \frac{F_s}{N}[/tex]
Substituting mg for N
[tex]\mu_s = \frac{F_s}{mg}[/tex]
Substituting values
[tex]\mu_s = \frac{467.88}{76 * 10}[/tex]
[tex]= 0.63[/tex]
