The speed of an artificial Earth satellite is 7.5 km / s How long does it take to orbit the globe if the satellite’s orbit is 45,000 km long?
Initial data: V (speed of an artificial Earth satellite) = 7.5 km / s; L (orbital length of an artificial satellite) = 45,000 km.
To calculate the time required for a satellite to fly around the Earth, you need to divide the length of its orbit by the speed of movement:
t = L / V = 45,000 / 7.5 = 6,000 s = 100 min = 1 h 40 min.
Answer: An artificial satellite will orbit the Earth in 1 hour and 40 minutes.
