Question

an artificial satellite is moving uniformly in a circular orbit of radius 42250km find it's speed if it takes 24hours to revolve around the earth
1769.4km​

Answer 1

Answer:

3.07km s^-1

Explanation:

s =2×22÷7×r

s=2×3.14×42250=265464.58km

there fore speed of satellite os

v=distance trvalled by time taken =265464.58÷24×60×60=3.07km/s^-1

Answer 2

Explanation:

Radius of satellite 42250

radius of earth(r)+height of satellite(h)=42250km

6400+height of satellite =42250km

height of satellite = 42250km - 6400

height of satellite =35,850km

Given => t= 24 hrs

$v = \frac{2\pi(r + h)}{t} \\ v = \frac{2 \times 3.14 \times 42250}{24} \\ v = 11,055.41km \: per \: second$

11,055.41 km/sec is velocity of satellite
