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

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

wavelength divides in half and speed stays the same.
