A 0.413 kg block requires 1.09 N of force to overcome static
friction. What is the coefficient
of static friction?
(No unit)

Explanation:

The equation for this is

f = μ where f is the frictional force the block needs to overcome, μ is the coefficient of static friction, and (that means that the normal force is the same as the weight of the block which has an equation of weight = mass times the pull of gravity). Filling in:

1.09 = μ(.413)(9.8) and

μ = so

μ = .27
