Question

An artificial satellite moves at an average distance of 1250 km above the centre of a planet. It takes 5 hours to complete one circuit. Calculate its average velocity in metres per second.

Answer 1

The average velocity of the artificial satellite is 69.44 m/s.

Step-by-step explanation:

To calculate the average velocity of the artificial satellite, we need to convert the average distance from kilometers to meters and the time taken from hours to seconds. The average distance of 1250 km is equivalent to 1,250,000 meters. The time taken of 5 hours is equivalent to 18,000 seconds. The average velocity is calculated by dividing the distance by the time:

average velocity = distance / time

Therefore, the average velocity of the satellite is 69.44 m/s.
