Question

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.
PLEASE ANSWER QUICK !!!!

Answer 1

Answer :-

Speed of the satellite is 11055.41 km/h .

Explanation :-

We have :-

→ Radius of the circular orbit = 42250 km

→ Time taken = 24 hours

________________________________

When a body is moving around a circular path, then it's speed is given by :-

v = 2πr/t

Where :-

• v is the speed of the body.

• r is radius of the path.

• t is time taken.

Substituting values, we get :-

⇒ v = (2 × 3.14 × 42250)/24

⇒ v = 265330/24

⇒ v = 11055.41 km/h

Answer 2

Question:-

• 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.

To Find:-

• Find the speed of satellite.

Solution:-

Given ,

• Radius of the orbit is 42250 km.

• Time taken is 24 hours.

Formula to be Used:-

• v = 2πr/t

Substitute in the Formula:-

$\dashrightarrow\sf \: v = \dfrac { 2 \times 3.14 \times 42250 } { 24 }$

$\dashrightarrow\sf \: v = \dfrac { 265330 } { 24 }$

$\dashrightarrow\sf \: v = 11055.416$

Hence ,

• Speed of Satellite is 11055.416
