003 10.0 points Earth orbits the sun once every 365.25 days. Find the average angular speed of Earth about the sun. Answer in units of rad/s. 004 (part 1 of 2) 10.0 points A disk with a radius of 0.1 m is spinning about its center with a constant angular speed of 10 rad/sec. What are the speed and magnitude of the acceleration of a bug clinging to the rim of the disk? 1. 1 m/s and 0 m/s2 (Disk...
The Earth has two main angular velocities as it moves through space. One is due to its motion around the sun, the other is due to its rotation around its own axis. A. What is the angular speed of the Earth as it revolves around the sun? (answer in rad/s) B. The radius of the Earth's orbit around the sun is about 1.5×108 km. Based on your answer to Part A, what is the tangential speed of the Earth as...
Earth has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Assume it is a uniform solid sphere. The distance of Earth from the sun is 1.50 x 1011 m. (Assume Earth completes a single rotation in 24.0 hours and orbits the Sun once every 365 Earth days.) (a) Calculate the angular momentum of Earth in its orbit around the Sun kg m2/s (b) Calculate the angular momentum of Earth on its axis kg...
001 10.0 points A car accelerates uniformly from rest and reaches a speed of 15.6 m/s in 4.5 s. The diameter of a tire is 35.6 cm. Find the number of revolutions the tire makes during this motion, assuming no slip- ping. Answer in units of rev. 002 10.0 points A figure skater begins spinning counterclock- wise at an angular speed of 4.2 π rad/s. Dur- ing a 4.6 s interval, she slowly pulls her arms inward and finally spins...

Chapter 08, Problem 40 The earth has a radius of 6.38 x 106 m and turns on its axis once every 23.9 h. (a) What is the tangential speed (in m/s) of a person living in Ecuador, a country that lies on the equator? (b) At what latitude (i.e., the angle in the figure, in degrees) is the tangential speed 1/5 that of a person living in Ecuador? Axis of rotation Equato (a) Number (b) Number Units D Units
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...
