J (b) What is the rotational kinetic energy (in J) of Saturn in its orbit around the Sun? (Assume its distance from the sun to be 1.43 ✕ 109 km and its period about the sun to be 10800 days.)...
Calculate the kinetic energy that the earth has because of its rotation about its own axis. Assume that the earth is a uniform sphere and that its path around the sun is circular. For comparison, the total energy used in the United States in one year is about 9.33 ✕ 109 J. J Calculate the kinetic energy that the earth has because of its motion around the sun.

A solid disk rolls down a ramp. Linear and rotational kinetic energy is recorded, as well as velocity. A hole is then drilled in the disk, the same data is recorded. Which has a higher velocity? Which has a higher rotational kinetic energy? Which has a higher linear kinetic energy?
Calculate the kinetic energy that the earth has because of (a) its rotation about its own axis and (b) its motion around the sun. Assume that the earth is a uniform sphere and that its path around the sun is circular. For comparison, the total energy used in the United States in one year is about 1.1 x 1020 J.

Calculate the rotational kinetic energy of a tire with a mass of 20.0 kg and a radius of 0.25m if the car is moving forward with a constant velocity of 8.5 m/s.
Estimate the kinetic energy of the Mars with respect to the Sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the Sun. [Assume the Mars is a uniform sphere with mass = 6.4×1023 kg , radius = 3.4×106 m , rotation period 24.7 h , orbital period 686 d and is 2.3×108 km from the Sun.]
Part A
Calculate the total rotational kinetic energy of the
molecules in 1.00 mol of a diatomic gas at 300 K.
Krot = ? J
Part B
Calculate the moment of inertia of an oxygen molecule (O2) for
rotation about either the y- or z-axis shown in
Figure 18.18 in the textbook. Treat the molecule as two massive
points (representing the oxygen atoms) separated by a distance of
1.21×10?10m. The molar mass of oxygen atoms is 16.0
g/mol.

What is the angular kinetic energy of the Earth due to its orbit around the sun? In Homework 10, you found the two main angular velocities of the Earth: one due to the Earth's motion around the sun, and one due to its rotation about its own axis. Now let's figure out the energy and momentum associated with that motion. IVO ALV O a ? For the purposes of this problem, treat the Earth as a solid, uniform sphere with...
