Question

An artificial sattelite is moving in a circular orbit of radius 42250km calculate its speed if it takes 24 hours to revolve around the earrth

Answer 1

v = 11061.02 km/h

Step-by-step explanation:

Given that,

The radius of the circular orbit, r = 42250 km

Time taken to revolve around the Earth, t = 24 hours

We need to find the speed of the satellite. We know that, speed of an object is equal to total distance traveled divided by the time taken. So,

`v=(2\pi r)/(T)`

Put all the values,

`v=(2\pi * 42250)/(24)\\\\v=11061.02\ km/h`

So, the speed of the satellite is equal to 11061.02 km/h.
