The following questions refer to two people each with mass m that are sitting on the outside edge of a massless and frictionless merry-go-round with radius R that is spinning with an initial angular velocity wo. 1. (Objective 29) One of the two people now pulls themselves halfway in to the center of the merry-go-round so that their new radius of rotation is In terms of wo, (i.e. as a multiple of wo) how much faster is the merry-go-round now spinning? 2. (Objective 27) a) By what factor did the kinetic energy of the system change when the person pulled themselves toward the center of the merry-go-round? b) What force did the work to change that kinetic energy?

The ball has a mass of 1 kg and is confined to move along the smooth vertical slot due to the rotation of the smooth arm OA. The rod is rotating with a constant angular velocityd slot at any instant. Which one of the following is (are ) incorrect answers ? =2 rad/s. Assume the ball contacts only one side of the ion e-2 rads Select one or more: There is only one contact force on the ball that is acting perpendicular to the rod. There are two contact forces on the ball: one is acting perpendicular to the wall, and the other is perpendicular to the rod. The path of the ball is given by r 0.5 sec 0. The acceleration along the 0 increasing direction is a, tan 6 sec 00 The normal reaction to the ball by the rod is given by the equation N gcos+ a, whiere ap s the acceleration along the 6 increasing direction.
An 8.79cm diameter floppy disk rotates at its fastest at 470 rpm. Part A: Express the angular velocity of the disk in revolutions per seconds? Part B: What is the time period of this revolution? Use scientific notation for your answer. Part C: What is the linear velocity of a point at the rim of the disk? Part D: What is the angular velocity at the center of the disk? Part E: If the disk took 3.2 sec to spin up to 470 rpm from rest, what was the average angular acceleration? How many revolutions did the disk complete within this time? What is the net displacement? Part F: If you turn off the floppy disk drive and the disk comes to a stop in 6.7 s, what is the average angular acceleration for this period of motion?
After a nuclear apocalypse on Earth, humans have built a space station known as the Ark. It has multiple sections controlled by different political factions, but one thing they all have in common is the need for artificial gravity. This is done in each section by setting a piece of the Ark spinning around the central axis of the station. The largest section of the station is a complete ring with a radius of 1000 m.a) What is the rotational velocity required to simulate gravity?b) One day on Earth is the defined by the amount of time it takes the Earth to rotate once around its axis and is 86,400 s. How many seconds is one “day” on this section of the station?c) When an inhabitant standing as they would on Earth, In which direction do their heads points? (which piece of the station)
Imagine that you could see a wheel spinning while speeding up, so you know that the angular velocity is (answer choice 1) , and the angular acceleration is (answer choice 2). But if instead the wheel is spinning counter clockwise and slowing down, so you know that the angular velocity is (answer choice 3) , and the angular acceleration is (answer choice 4). answer choices: out of page (positive) or into page (negative)

To throw the discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.8 m. If the thrower takes 0.90 s to complete one revolution, starting from rest, what will be the speed of the discus at release? Express your answer in meters per second.
