Homework Statement
Given: The coefficient of static friction between the person and the wall is 0.66, the mass of the person is 73 kg, the radius of the cylinder is 7 m, and g = 9.8 m/s.
A barrel of fun consists of a large vertical cylinder that spins about the vertical axis. When it spins fast enough, any person inside will be held up against the wall.
Find ώc, the critical angular speed below which a person will slide down the wall of the cylinder. Answer in units of rad/s.
Homework Equations
Ac = V^2.r or ώ^2=Ac
µ = ώ^2r/g
The Attempt at a Solution
So I used µ = ώ^2r/g and solved for ώ but it was wrong...
That's basically it.
What did I do wrong?
