Q. A large vertical cylinder spins about its axis fast enough that any person inside is held up against the wall when drops away from the floor. The coefficient of static friction between person and the wall is u, = 0.35, and the radius of cylinder r = 2m. What is the maximum (linear) speed necessary to keep person from falling?

At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 2.72 m/s, and an 82.0-kg person feels a 276-N force pressing against his back. What is the radius of a chamber?
Problem 1 Seeing Double Two blocks are connected to one another with ropes as shown on a frictionless table.

In an amusement park ride, a child stands against the wall of a cylindrical room that is then made to rotate. The floor drops downward and the child remains pinned against the wall. If the radius of the room is 2.15 m and the relevant coefficient of friction between the child and the wall is 0.600, with what minimum speed is the child moving if he is to remain pinned against the wall? 07.26 m/s O3.93 m/s O 12.1 m/s 5.93 m/s 9.80 m/s
