Two spheres are each rotating
at an angular speed of 24.6 rad/s about axes that pass through
their centers. Each has a radius of 0.400 m and a mass of 1.68 kg.
However, as the figure shows, one is solid and the other is a
thin-walled spherical shell. Suddenly, a net external torque due to
friction (magnitude = 0.330 N · m) begins to act on each sphere and
slows the motion down. How long does it take (a) the...
Two spheres are each rotating at an angular speed of 24.9 rad/s about axes that pass through their centers. Each has a radius of 0.450 m and a mass of 1.31 kg. However, as the figure shows, one is solid and the other is a thin-walled spherical shell. Suddenly, a net external torque due to friction (magnitude = 0.280 N m ) begins to act on each sphere and slows the motion down. How long does it take (a) the...

What is the translational speed of the frozen juice can when it reaches the bottom? (a) Number Units (b) Number Units Click if you would like...
Two thin rods of length L are rotating with the sameangular speed ω (in rad/s) about axes that passperpendicularly through one end. Rod A is massless but has aparticle of mass 0.66 kg attached to its free end. Rod B has a massof 0.66 kg, which is distributed uniformly along its length. Thelength of each rod is 0.77 m, and the angular speed is 5.7 rad/s.Find the kinetic energies of rod A with its attached particle andof rod B.
A) in minutes
B) in launched pairs
C) in rad/s
All of the questions on this exam concern a space station, consisting of a long thin uniform rod of mass identical uniform hollow spheres, each of mass D E 74-meters, attached at the ends of the rod, as shown below. Note that none of the diograms shown is drawn to scale 4 4x 10° kg and length C. 4.4 x10 kg and l length C.240 meters, with two 17-'x 106kg...
These questions concern a space station, consisting of a long
thin uniform rod of mass 4.3 x 10^6 kg and length 769 meters, with
two identical uniform hollow spheres, each of mass 1.7 x 10^6 kg
and radius 218 meters, attached at the ends of the rod, as shown
below. Please note that none of the diagrams shown is drawn to
scale.
A. Suppose that the station starts out at rest (not rotating).
What we want is to get it...
