Ladybug A begins walking towards the center of the disk. What happens to the angular speed of the disk bug system?

A woman passes through a door with a tangential speed of 1.8 m/s from the center of the door, what is the door’s angular speed?

A planet rotates through one complete revolution every 27 hours. Since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 27 hours. Find the angular velocity of a person standing on the equator

The paths of two small satellites, X and Y, of equal mass of 4.00 kg each, are shown below. They orbit around a massive star, as illustrated, with M = 6.20x1029 kg The orbits are in the plane of the paper and are drawn to scale. %3D a C In the statements below KE is kinetic energy, PE is potential energy, and L is magnitude of the angular momentum.

The figure shows multiple solid disks with uniform mass distribution that are spinning about its center. The mass of the disks are the same, but they have different radii, as shown. Rank the disks by the amount of energy needed to spin the disk so that the outer edge of the disk has linear velocity v, from greatest to least. Explain your reasoning. A B с

I need some help. Can you walk me through how to solve this problem? 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 1.9 m. If the thrower takes 1.2 s to complete one revolution, starting from rest, what will be the speed of the discus at release?

At it's peak, a tornado is 75m in diameter and carries 470m/s wind at its outer edge. What is it's angular speed in radians per second?

lo completes one orbit about Jupiter in 1.77 days and the average Jupiter-Io distance is 4.22 x 10° m. Calculate the angular speed w of Io as it orbits Jupiter. W =

A kid runs towards the edge of a merry-go-round that is not rotating and jumps on. The merry-go-round then rotates with a constant angular velocity ω. Assume that the kid has a mass of 40 kg and is initially running at a speed of 2 m/s tangent to the edge of the merry-go-round. The merry-go-round is a uniform disk with a mass of 120 kg and a radius of 2 m. Assume that it rotates without friction. What is the final angular velocity ωf (in radians/s) of the merry-go-round (with the kid riding)?   Please write out steps, not type-I have dyslexia
