Question

An artificial satellite is moving in a circular orbit of radius 36,000 km. Calculate its speed if it takes 24 hours to revolve around the earth.

Answer 1

Answer:

9,420 km/hr

Explanation:

Given:

• Radius of the circular orbit = 36,000 km

• Time taken to revolve around the earth = 24 hours

To find:

• Speed of the artificial satellite

Speed = $\frac{Distance}{Time}$

Distance will be equal to the circumference of the orbit

Circumference of the orbit = $2 \pi r$

Circumference = $2 \times 3.14\times 36,000$

Circumference = $6.28 \times 36,000$

Circumference = 2,26,080 kilometres

Speed of the artificial satellite = $\frac{226080}{24}$

Speed of the artificial satellite = 9420 km/hr

The artificial satellite is moving with a speed of 9,420 km/hr
