The Singapore Flyer (a diameter of 155 m) rotates clockwise with a constant rate ω = 0.6 radians per second. Dr. Greco, a 80 kg passenger, is riding in the gondola at an angle of 40 degrees from the horizontal as shown.
(a) What is the magnitude of the parallel component of the contact force exerted by the Ferris wheel on Dr. Greco?
(b) What is the magnitude of the perpendicular component of the contact force exerted by the Ferris wheel on Dr. Greco? On the diagram, indicate the direction of the contact force acting on Dr. Greco.

A Ferris wheel with radius 8.5 m initially rotates clockwise at a constant rate by completing 2.00 rev in 28.00 s. It then begins to decelerate at a rate of 0.50 rad/s2 with its only passenger at the top of the wheel. Find the direction of the total acceleration vector. Express your answer as a positive number with respect to the positive x-axis. Choose up and to the right as your positive direction.
A 54.0-kg child takes a ride on a Ferris wheel that rotates four times each minute and has a diameter of 20.0 m. (a) What is the centripetal acceleration of the child? (b) What force (magnitude and direction) does the seat exert on the child at the lowest point of the ride? (c) What force does the seat exert on the child at the highest point of the ride? (d) What force does the seat exert on the child when the child is halfway...
3. A person takes a ride on a 20-meter-diameter Ferris wheel that rotates with a constant speed of 10 radians per second. Calculate the magnitude and direction of the force that the seat exerts on a 10 kilogram person when he is (a) at the top of the wheel, (b) at the bottom of the wheel, and (c) halfway up the wheel. 4. A thin, uniform rod of length L and mass M swings from a pivot at one end,...
A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
