Calculation of the Speed Required for an Artificial Satellite in a Circular Orbit

To determine the speed required for an artificial satellite to orbit the Earth at a height of 500 km, we can use the principles of circular motion and gravitational force.

The speed required for an object to maintain a circular orbit around the Earth can be calculated using the formula:

v = √(GM/r)

Where: - v is the required speed of the satellite - G is the gravitational constant (approximately 6.67430 × 10^-11 m^3 kg^-1 s^-2) - M is the mass of the Earth (approximately 6 × 10^24 kg) - r is the radius of the orbit (which is the sum of the Earth's radius and the height of the orbit)

Given that the mass of the Earth is 6 × 10^24 kg and the radius of the Earth is 6400 km, we can calculate the radius of the orbit:

Radius of the orbit = Radius of the Earth + Height of the orbit

Radius of the orbit = 6400 km + 500 km

Converting the radius of the orbit to meters:

Radius of the orbit = (6400 km + 500 km) × 1000 m/km

Now, we can substitute the values into the formula to calculate the required speed:

v = √((6.67430 × 10^-11 m^3 kg^-1 s^-2) × (6 × 10^24 kg) / (Radius of the orbit))

Let's calculate the value of the radius of the orbit and the required speed.
