A man-made satellite orbits the earth in a circular orbit that has a radius of 21000 km. The mass of the earth is 5. 97e 24 kg. What is the tangential speed of the satellite?.

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Ais the answer hope this

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
