Question

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

Answer 1

The artificial satellite takes 24 hrs to travel 42250 km
Speed= distance/time= 42250/24= 1760.41 km/h.

Answer 2

Here's your answer...

The linear velocity of a body in rotational motion is given by the relation
v = wr
where w is the angular velocity and r is the radius.

For t = 24 hours...

$w = \frac{2\pi}{t} \\ w = \frac{2\pi}{24} = \frac{\pi}{12}$
$v = wr \\ = \frac{\pi}{12} \times 42250$
≈ 11061.02 km/hr
