An amusement park ride consists of a large vertical wheel of radius R that rotates counterclockwise on a horizontal axis through its center, as shown below.
The cars on the wheel move at a constant speed v. Points A and represent the position of a car at the highest and lowest point of the ride, respectively. A person of weight Fg sits upright on a seat in one of the cars. As the seat passes point A the seat exerts a normal force with magnitude 0.8 Fg on the person. While passing point A the person releases a small rock of mass m, which fails to the ground without hitting anything.

An amusement park ride consists of a rotating circular platform 11.6 m
011An amusement park ride consists of a rotating circular platform 11.6 m in diameter from which 10 kg seats are suspended at the end of 3.1 m massless chains. When the system rotates, the chains make an angle of 13.8° with the vertical. The acceleration of gravity is 9.8 m/s2 What is the speed of each seat? Answer in units of m/s. 012 If a child of mass 38.2 kg sits in a seat, what is the tension in the chain (for the same angle)? Answer...

A Ferris wheel is a vertical, circular amusement ride with radius 8.5 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at a constant rate, going around once in 7.3 s. Consider a rider whose mass is 73 kg. a. At the bottom of the ride, what is the vector gravitational force exerted by the Earth on the rider? b. At the top of the ride, what is the rate of change of the rider's...

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...
