004 (part 1 of 2) 10.0 points An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that any person inside is held up against the wall when the floor drops away. - 6.18 m W What is the minimum angular velocity Wmin needed to keep the person from slipping downward? The acceleration due to gravity is 9.8 m/s², the coefficient of static friction be-
tween the person and the wall is 0.68, and the radius of the cylinder is 6.18 m. Answer in units of rad/s. 005 (part 2 of 2) 10.0 points Suppose the person, whose mass is m, is be- ing held up against the wall with an angular velocity of w 2 wmin. = The magnitude of the frictional force be- tween the person and the wall is 1 1. F = mg. 5 2. F = 3mg. 1 3. F = 4. F = mg. 5. F=4mg. 6. F= 2mg. 1 == mg. 7. F 4 8. F = mg. mg. 2 9. F = 5mg.
