P8 Megan is standing at the edge of a disk of that is spinning at constant angular velocity o. In this position, her centripetal acceleration is a. Please answer each of the following questions. You answers should be written in terms of the given variables: ω and a a) What is Megan's velocity? b) Megan now moves towards the center of the disk until her acceleration is one half its orig value. How far is she from the center?

A mouse steps onto the edge of a disk of radius R that is
spinning at a constant angular speed of , rad/second
(assume counterclockwise rotation). The mouse moves with the
constant velocity towards the cheese,
located at the center of the rotating disk.
(a) Derive a differential equation for the path of the mouse in
polar coordinates.
(b) How many revolutions will the disk make before the mouse
gets the cheese? The solution should be in terms of ,...

Alex and Riley are two kids standing on a merry-go-round. Alex has half the mass of Riley and is standing at the very edge of the merry-go-round. Riley is standing halfway between the edge and the center of the merry-go-round. The merry-go-round is turning at a constant rate. Which of the following are true? (Select all that apply.) Alex has the larger moment of inertia on the merry-go-round. Riley has the greater angular velocity. Alex has the larger tangential...

Three children are riding on
the edge of a merry-go-round that has a disk of mass 102 g, radius
1.9 m, and is spinning at 16 rpm. The children have masses of 23.2
kg, 26.4 kg, and 33.4 kg. If the child who has a mass of 26.4 kg
moves to the center of the merry-go-round, what is the new
magnitude of angular velocity in rpm?

1. Two childre, each with a mass of 22.1 kg are standing on the edge of a merry go round that is spinning with an angular veloctiy of 2.1 rad/s. The merry go round has a mass of 115 kg and a radius of 1.45m. a. The children can be treated as particles and the merry go round can be treated like a spinning disk. Treating them this way, what is the total moment of inertia of thr children and...

A speck of dust on a spinning DVD has a centripetal acceleration of 15 m/s2 . What is the acceleration of a different speck of dust that is twice as far from the center of the disk? What would be the acceleration of the first speck of dust if the disk's angular velocity was doubled? Please express your answer to two significant figures and include the appropriate units.

Three children are riding on the edge of a merry-go-round that is a disk of mass 110 kg, radius 1.7 m, and is spinning at 16 rpm. The children have masses of 22.8 kg, 26.4 kg, and 31 kg. M = 110 kg m1 = 22.8 kg m2 = 26.4 kg m3 = 31 kg r = 1.7 m f = 16 rpm If the child who has a mass of 26.4 kg moves to the center of the merry-go-round,...

Q.3 A solid disk with a mass of 36 kg and a radius of 0.7 m is spinning around an axis through its center, it rotates with an angular speed of 3 full turns per second. You drop a 12 kg mass onto the disk at the edge, it sticks to the disk, reducing the angular speed to ws. Next you apply a 30 N force tangentially at the edge of the disk to slow it...
