A.) Calculate the period of the satellite?

B.) Calculate the speed of the satellite?

For A. i got 5451s

and for B. i got 7722m/s

can anyone tell me if that's what they got too?

also...

CAlculate the frequency of with which the Earth would have to rotate so that an object on the surface of the Earth at the equator would just become "weightless"(all of the gravitational force on it would be necessary to keep the object in its "orbit" as the Earth rotated.)

So for this one, my final answer , my frequency was 1.97 x 10^-4.,..and by the way, what would be the units for frequency here?

for this question, my centripetal acceleration , i used 9.8m/s^2..

thanks for anyones help in advance!
