Question

Question 1 (of 3) alue: 5.00 points A The rotor (see the figure below) is an amusement park ride where people stand against the inside of a cylinder. Once the cylinder is spinning fast enough, the floor drops out. (a) What force keeps the people from falling out the bottom of the cylinder? (select) (b) If the coefficient of friction is 0.390 and the cylinder has a radius of 2.30 m, what is the minimum angular speed of the cylinder so that the people don't fall out? (Normally the operator runs it considerably faster as a safety measure.) ideur oiuter car bedoout or aiape rad/s References eBook & Resources

Explanation / Answer

a) frictional force

is the force which is keeping the people from falling out.

b) u= 0.390

r = 2.30 m

let the angular speed is w

m * g = u * m * w^2 * r

9.8 = 0.390 * w^2 * 2.30

w = 3.31 rad/s

the final angular speed is 3.31 rad/s
