ω = 2*pi/T = 2*pi/4.4 =1.428
at top Fpush = mrω^2 - mg = 59 *(9*1.428^2 - 9.8) =504.61N
at bottom Fpush =mrω^2 + mg =59 *(9*1.428^2 + 9.8) =1661.0 N
mrω^2 = mg ==> ω = sqrt(g/r);ω =1.09 rad/sec
T = 2*pi/1.088 =5.774 seconds
In an amusement park ride called The Roundup, passengers stand inside a 18.0m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, as shown in the figure.Part A) Suppose the ring rotates once every 4.20s. If a rider's mass is 55.0kg, with how much force does the ring push on her at the top of the ride?Part B) Suppose the ring rotates once every 4.20s. If a rider's mass is 55.0kg, with how much force...

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...
In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 50.00 in a time of 8 s. The combined mass of the car and riders is 5.50*103 kg. Find the average net force exerted on the car and riders by the magnets.
11. “The Rotor”. The amusement park ride known as “the rotor”, essentially a large hollow cylinder, rotates rapidly about a central axis. Riders stand on the floor up against the wall of this ride before it begins to rotate. Once the ride starts, all riders, the wall, and floor begin to rotate rapidly and undergo uniform circular motion. When the rotation speeds reaches a certain value, the floors fall away and the riders are held pinned against the wall where...
Sam's job at the amusement park is to slow down and bring to a stop the boats in the log ride. If a boat and its riders have a mass of 1200 kg and the boat drifts in at 1.4 m/s how much work does Sam do to stop it? W=___ J

The Sidewinder is a shuttle type steel rollercoaster. The rollercoaster cart starts at the bottom of the frictionless track and is accelerated from a stand still over a distance of 7 meters. Then the cart enters the loop, rises to the top with just enough velocity to keep from stalling at the top of the loop. Gaining velocity the cart finishes the loop, bottoms out, and then rises up the vertical segment of the track. After stalling out at a...
