Asatellite is in circular orbit 1000 miles (1.61 x 10 m) above the earth. how long does it take this
satel te to complete one orbit?
(the radius of the earth is 6.4 x 10^m and g = 6.67 x 10" n-m-/kg-)

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
