What is the approximate tangential speed of a 2000 kg satellite that is in a circular orbit at an altitude of 125 km above Earth

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
