constant speed on a circle ((r = 12.0 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is
0.840, and the angle 0 in the drawing is 12.9°. How much time is required for your suitcase to go around once? Assumme that the static

An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it rotates around its axis. Once the Rotor reaches its operating speed, the floor drops but the riders remain pinned against the wall of the cylinder. Suppose the cylinder makes 24.5 rev/min and has a radius of 3.70 m.
What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?
A Wall of Death is a carnival show featuring a motorcyclist rides along the vertical wall of the cylinder and performs various stunts while doing so. Given that the radius of the cylinder is 7 m and the static coefficient of friction is 0.8, what is the minimum speed in m/s2 that the motorcyclist must do to prevent the motorcycle to slip from the wall?

The directions of the three forces and the acceleration must be identified. Make a free-body diagram. Please use the blue vector to specify forces and the pink vector for acceleration.

The turntable has a fixed period of rotation, T=4.83 s. The coin is carefully and successively placed at ever larger radial distances from the center of the turntable (where its axis of rotation lies). The coefficient of static friction between the coin and turntable is μs=0.025. a. At an arbitrary radial distance r of the coin from the axis of rotation, what is the maximum speed Vmax the coin can have without slipping relative to the surface of the turntable? (This will be a symbolic answer in terms of μs, g, and r.) b. Use the given period of the turntable’s motion along with the answer from question a to determine the maximum distance the coin can be placed from the center of the turntable and still not slip relative to the table’s surface.arrow_forward
