Question

25 n object requires a 5. 0 n to start moving over a horizontal surface. What is the coefficient of static friction?.

Answer 1

μ=1/5=0.2

Step-by-step explanation:

using the formula

Fs=Fn*μ

Where

Fs is the static force

Fn = Normal force

μ= coefficient

so if Fn=25n

and it requires 5 n to start moving, means the max Fs is 5n

5=25μ

μ=5/25

μ=1/5=0.2
