Please help! circular motion
At what height above teh Earth's surface would a satellite have to orbit in order that it be stationary in reference to a point on the earth? b. what would be it's speed? c. How would you describe the general location of that point in relation to the Earth's surface?
Fg= (G)(M1M2)
r2
G=6.67x10-11Nm2/kg2
Fw=Mg
Fc=M v2
r
a=v2
r
Earth mass=6x1024kg
Earth radius=6.4x106m
Can someone help me and let me know where to start? I know how to find the velocity, but seems like i don't have enough information? is there something I'm missing?? please help!
