Question

an artificial satellite is moving in a circular orbit of radius 42250 km.​

Answer 1

Answer

Distance covered by the satellite in 24 hours

s=2πr

=2×3.14×42250=265464.58 km

Therefore speed of satellite,

v=

time taken

distance travelled

=

24×60×60

265464.58

=3.07 km s

Answer 2

Answer: 3.07 km/s

Explanation:

Distance covered by the satellite in 24 hours

S = 2πr

= 2 × 3.14 × 42250 = 265464.58 km

Therefore speed of satellite,

$v = \frac{distance travelled}{time \: taken}$

$= \frac{265464.58}{24 \times 60 \times 60}$

= 3.07 km/s
