Question

a satellite is said to be in geosychronous orbit if it rotates around the earth ones everyday.for the earth all satellites in geosychronous orbits must rotate and a distance of 4.23 from the eaearth what is the magnitute of accelearation

Answer 1

The acceleration felt by any object in uniform circular motion is given by a =  . We are given the radius but must find the velocity of the satellite. We know that in one day, or 86400 seconds, the satellite travels around the earth once. Thus:

v =  =  =  = 3076 m/s

thus

a =  =  = .224 m/s2

I have some dout on answer 90% correct
