4. Use the results on page 300 of the textbook to do the following: solid, uniform disk has a mass of 35.0 kg and outer radius 40.0 cm. Attached to the disk at a point 270 cm from the disk's center is a heavy metal bolt of mass 1.00 kg. By what percentage does the bolt increase the overall moment of inertia around an axis through the disk's center (and perpendicular to the plane of the disk)? Treat the bolt...

5*) Find the angular velocity of the Earth due to its daily
rotation and express it in radians per second. Then use it, and a
model of the Earth as a solid sphere of mass M=
5.97 × 1024 kg and radius R
= 6.37 × 106 m, to estimate the angular momentum of the Earth due
to its rotation around its axis. (The result should be of the order
of 1033 kg m2/s. This is called the Earth’s “intrinsic”...

10*) The Sun has approximate radius 7×108 m, and rotates around
its axis once every 27 days. a) Find its angular velocity in rad/s,
and (assuming it is a uniform sphere) write a formula for its
angular momentum expressing it in terms of its mass M (you do not
need to substitute a value for M). b) Suppose the Sun were to
collapse to a neutron star, which is a much denser state, without
losing any mass and without being...

A uniform cylinder of radius r15.0 cm and mass m 1.70 kg is rolling without slipping on a horizontal tabletop. The cylinder's center of mass is observed to have a speed of 4.60 m/s at a given instant. (a) What is the translational kinetic energy of the cylinder at that instant? J (b) What is the rotational kinetic energy of the cylinder around its center of mass at that instant? J (c) What is the total kinetic energy of the...

A uniform hoop rolls without slipping down a 19° inclined plane. What is the acceleration of the hoop's center of mass? The moment of inertia of a uniform solid disk about an axis that passes through its center = mr². The moment of inertia of a uniform solid disk about an axis that is tangent to its surface = 2mr².
