A stick of length l = 65.0 cm rests against a wall. The coefficient of static friction between stick and the wall and between the stick and the floor are equal. The stick will slip off the wall if placed at an angle greater than θ = 39.0 degrees. What is the coefficient of static friction, μs, between the stick and the wall and floor?
μs=
anyone solved this ?????
To find the coefficient of static friction (μs) between the stick and the wall and floor, we can use the condition for the stick to slip off the wall:
tan(θ) = μs
Given that θ = 39.0 degrees, we can plug it into the equation and solve for μs:
tan(39.0) = μs
Using a scientific calculator, find the tangent of 39.0 degrees and you'll get:
μs ≈ 0.8001
Therefore, the coefficient of static friction (μs) between the stick and the wall and floor is approximately 0.8001.
