Answer:
Fs = 17.66 N
Explanation:
The force of static friction is given by the following formula:
[tex]F_s = \mu R = \mu W\\[/tex]
where,
Fs = The force of static friction = ?
μ = coefficient of static friction = 0.9
W = weight of sneakers = mg
m = mass of sneakers = 2 kg
g = acceleration due to gravity = 9.81 m/s²
Therefore,
[tex]F_s = \mu mg\\F_s = (0.9)(2\ kg)(9.81\ m/s^2)\\[/tex]
Fs = 17.66 N
