One of the rides found at carnivals is the rotating cylinder. The riders step inside the vertical cylinder and stand with their backs against the curved wall. The cylinder spins very rapidly, and at some angular velocity, the floor is pulled away. The thrill-seekers now hang like flies on the wall. If the radius of the cylinder is 5 m and the coefficient of static friction between the people and the wall is 0.4, what is the maximum period (in...

An amusement park ride has a vertical cylinder with an inner radius of 4 m, which rotates about its vertical axis. Riders stand inside against the carpeted surface and rotate with the cylinder while it accelerates to its full angular velocity. At that point the floor drops away and friction between the riders and the cylinder prevents them from sliding downward. The coefficient of static friction between the riders and the cylinder is 0.91. What minimum angular velocity in radians/second...

One of the more sadistic rides at amusement parks is the “gravitron”. This is a vertical cylinder with a radius of 1.5 m. People stand inside the cylinder, against the wall. The cylinder spins, and once people reach a sufficient velocity the floor drops out from under them, leaving them stuck on the wall. If the minimum coefficient of static friction between the people and the wall is µs = 0.70, what must be the minimum linear velocity of the...

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. If the coefficient of static friction between the person and the wall is 0.563 and the radius of the cylinder is 8.87 m, what is the minimum tangential speed necessary to keep a person from falling? ____ m/s What is the maximum period of rotation to keep a...

An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that a person inside is stuck to the wall and does not slide down when the floor drops away. The acceleration of gravity is 9.8 m/s 2 . Given g = 9.8 m/s 2 , the coefficient µ = 0.564 of static friction between a person and the wall, and the radius of the cylinder R = 4.9 m. For simplicity, neglect the...

An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that a person inside is stuck to the wall and does not slide down when the floor drops away. The acceleration of gravity is 9.8 m/s2. Given g = 9.8 m/s2, the coefficient μ = 0.569 of static friction between a person and the wall, and the radius of the cylinder R = 5.4 m. For simplicity, neglect the person’s depth and assume...

3. Rotor (6 points) The Rotor is an amusement park ride consisting of a large, vertical cylinder with radius R- 2.5 m. A rider stands on the inside wall, and the cylinder begins rotating. When the angular velocity is high enough, the floor is lowered but, due to static friction, the rider does not slide down the wall. Suppose the Rotor is spinning with an angular velocity of 4 rad/s. (a) (2 points) How much time does it take for...

An amusement park ride consists of a rotating vertical cylinder
with rough canvas walls. The floor is initially about halfway up
the cylinder wall as shown. After the rider has entered and the
cylinder is rotating sufficiently fast, the floor is dropped down,
, yet the rider does not slide down. The rider has mass of 50 kg.
The diameter of the cylinder is 6.5 meters. The coefficient of
