Using the following data calculate the speed of the earth in its orbit in miles/hr. Mean Radius of Orbit = 1.5 x 1011 m 1 mile = 1.61 km. Mass of Sun = 1.99 x 1030 kg G = 6.67 x 10-11. 12. (I) Calculate the force of gravity on a spacecraft 12,800 km (2 earth radii) above the Earth’s surface if its mass is 1400 kg. 13.

Taking the Earth to be a uniform sphere with dimensions as given above, compute its angular momentum about its spin axis. A small particle of mass 0.2 kg is being whirled in a horizontal circle at the end of a 2m long string at a constant speed of 1m/s. Determine its angular momentum about its axis of rotation.
How Fast Does the Earth Spin?
The speed of rotation at Earth’s Surface differs depending on your latitude. Greatest speed at equator. Slowest speed at poles. b. Revolution. 1. Revolution – Earth revolving around the sun. Orbits. the sun once each year. Revolves 1° per day. Takes 365 ¼ days to make a full revolution .
