A thin uniform rod has a length of 0.530 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.41 rad/s and a moment of inertia about the axis of 3.10×10−3 kg⋅m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end of...

Two identical thin rods of mass M and length d are attached
together in the form of a plus sign “+” (see figure 9). The whole
structure is rotating counterclockwise with angular velocity of ω
about the z axis (which is at the point of attachment). The angular
momentum about the z axis is:

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 22.0 rad/s about axes that pass through their centers. Each has a radius of 0.430 m and a mass of 1.64 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 = 0.150 N·m) begins to act on each sphere and slows the motion down. How long does it take (a) the solid sphere...

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...
