Question

0. An artificial satellite is moving in a circular orbit of radius 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth. ​

Answer 1

Given:-

• An artificial satellite is moving in a circular orbit of radius 42250 km.
• Time= 24 hours.

To Find:-

• Speed of satellite after 24 hours to revolve around the Earth.

Solution:-

For finding the speed of satellite ,first we need to find the distance that has been covered by satellite in 24 hour

$\sf\huge \: distance = 2\pi \times r$

$= > 2×3.14×42250km$

$= > 6.28 \times 42250km$

$= > 265464.58 km$

We know that

$\sf\huge \: speed = \frac{distance}{time}$

So,

Speed of Satellite =

$\frac{distance \: covered}{time \: taken}$

$= > v = \frac{265464.58}{24}$

$= > v = \frac{265464580m}{24 \times 60 \times 60s}$

$= > v = 3137m {s}^{ - 1}$

∴The speed of satellite that it takes 24 hours to revolve around the earth is 3137m/s
