A common carnival ride, called a gravitron, is a large cylinder in which people stand against the wall of the ride as it rotates. At a certain point the floor of the cylinder lowers and the people are surprised that they don't slide down. Suppose the radius of the cylinder is r = 15 m, and the friction between the wall and their clothes is μs = 0.54. Consider the tangential speed v of the ride's occupants as the cylinder spins. 1.) what is the minimum speed in m/s that the cylinder must make a person move at to ensure they will stick to the wall? 2.) what is the frequency in revolutions per minute of the carnival ride when it has reached the minimum speed to stick someone to the wall?

A solid sphere is released from the top of a ramp that is at a height h1 = 2.45 m. It rolls down the ramp without slipping. The bottom of the ramp is at a height of h2 = 2.14 m above the floor. The edge of the ramp is a short horizontal section from which the ball leaves to land on the floor. The diameter of the ball is 0.13 m. a) Through what horizontal distance d, in meters, does the ball travel before landing? b)How many revolutions does the ball make during its fall?
A professor sits on a rotating stool that is spinning at 10.0 rpm while she holds a heavy weight in each of her hands. Her outstretched hands are 0.795 m from the axis of rotation, which passes through her head into the center of the stool. When she symmetrically pulls the weights in closer to her body, her angular speed increases to 20.5 rpm. Neglecting the mass of the professor, how far are the weights from the rotational axis after she pulls her arms in?

A certain amusement park ride consists of a large rotating cylinder of radius R = 3.15 m. As the cylinder spins, riders inside feel themselves pressed against the wall. If the cylinder rotates fast enough, the frictional force between the riders and the wall can be great enough to hold the riders in place as the floor drops out from under them. If the cylinder makes f 0.590 rotations/s, what is the magnitude of the normal force FN between a rider and the wall, expressed in terms of the rider's weight W? FN = W What is the minimum coefficient of static friction u, required between the rider and the wall in order for the rider to be held in place without sliding down? Hs 2

A solid disk of uniform density and mass M = 0.950 kg with radius R = 0.250 m is suspended vertically and is free to rotate about its center without friction. A point object that has the same mass as the disk is placed at an angle 0 = 25.0° clockwise from the top along the rim, causing the disk to rotate. The acceleration due to gravity is g=9.81m/s². What is the angular speed wf of the disk when the point object is directly below the center of the disk? R 0.

A turntable with a mass of 12 kg and a radius of 2 meters spins at a constant angular velocity of 140 rpm. A 500-gram scoop of uniformly-dense ice cream falls onto the turntable, so the scoop's center of mass is one meter away from the turntable's center. The scoop forms a hemisphere and has a radius of 4 cm. If there's no friction between the brick and ice cream scoop and they spin at the same angular speed, what is their final angular speed, in rev/min or in rad/s? Justify your answer with your rationale and equations used.
