Is there another way to answer this question with the information given in the question and any assumptions that can be made from it?

I know the velocity has to be less than 11 km/sec (escape velocity).

would the period of the satellite be equal to the period of the Earth? If so it would be 24 hours or 86400 seconds (SI units) and how would that be incorporated into the problem?

I don't know how to answer this question without a given altitude, but since one isn't given then I probably don't need one. Any ideas? Determine the minimum velocity an Earth satellite must have in order to purse a stable orbit without falling to the ground.

I don't quite know what formula to use. Is it V= omega x radius or arc length= velocity x time? Do I add the velocity of both discs or is it just on velocity?

So, if one revolution is 360 degrees and 1 degree is 60 minutes, then 3 seconds would be 3 seconds/3600 seconds = 8.333e-4 degrees?

It would be 50 revolutions every 3 seconds.

I know that 1000 rev/min is about 105 radians/second. The frequency is 16.7 Hz and the time would be 0.0599 seconds. But, I don't know how to find the angle.

Angular Speed Question, Please Help! I have this question I am stuck on and I don't understand and need help: In a neutron velocity selector, two thin discs of a neutron absorbing material are rigidly mounted on a shaft 1 meter apart and rotated with constant angular speed of 1000...

I'm having trouble solving part of this problem. Can anyone help? In climbing a wall, a caterpillar undergoes a complicated motion in which it ascends 3m and slips down 2m every 5min. What is its average speed and average velocity after 5min? I figured the avg. speed to be 0.02 m/s, but...
