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: o 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 original value. How far is she from...
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 ,...
A person with mass mp = 76 kg stands on a spinning platform disk
with a radius of R = 1.89 m and mass md = 191 kg. The disk is
initially spinning at ω = 1.6 rad/s. The person then walks 2/3 of
the way toward the center of the disk (ending 0.63 m from the
center).
1)
What is the total moment of inertia of the system about the
center of the disk when the person stands on...
4)A large disk of mass Md and radius R is spinning in a horizontal plane about a vertical axis through its center with a given angular velocity of omega. A person of mass Mp (initially at the center of the disk and not spinning, let's say) then walks out to the edge of the disk (yes, the disk is that large!). Find the final angular velocity of the disk (with the person standing on its edge).Treat the person as a...
A person with mass mp = 79 kg stands on a spinning platform disk with a radius of R = 1.86 m and mass md = 183 kg. The disk is initially spinning at ω = 1.8 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.62 m from the center). 1) What is the total moment of inertia of the system about the center of the disk when the person stands on...
A person with mass ma = 75 kg stands on a spinning platform disk with a radius of R = 1.71 m and mass m-188 kg. The disk is initially spinning at ω = 1 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.57 m from the center). 1)What is the total moment of inertia of the system about the center of the disk when the person stands on the rim of...
A person with mass mp = 79 kg stands on a spinning platform disk with a radius of R = 1.83 m and mass md = 183 kg. The disk is initially spinning at ω = 1.8 rad/s. The person then walks 2/3 of the way toward the center of the disk (ending 0.61 m from the center). 5) What is the centripetal acceleration of the person when she is at R/3?
A disk with a mass of 15 kg is spinning about its center with a constant angular acceleration applied to it. Its c value is 1/2 about its center and it is initally spinning at 5 rad/s clockwise. If the disk stops spinning in a time of 1.5 s, how many revolutions does the disk make until it stops? 1.79 rev. 3.75 rev. 11.25 rex 0.60 rev. MacBook Pro $ % 5 & 7 8 E R T Y F...
A disk with a diameter of 0.06 m is spinning with a constant velocity about an axle perpendicular to the disk and running through its center. 1) How many revolutions per second would it have to rotate in order for the acceleration of the outer edge of the disk to be 12 g's (i.e., 12 times the gravitational acceleration g)? f = 2) For the frequency determined in part (a), what is the speed of a point half way between...
A person with mass mp = 74 kg stands on a spinning
platform disk with a radius of R = 2.37 m and mass md =
184 kg. The disk is initially spinning at ? = 1.9 rad/s. The person
then walks 2/3 of the way toward the center of the disk (ending
0.79 m from the center).
1) What is the total moment of inertia of the system about the
center of the disk when the person stands...
