A satellite is orbiting earth at a distance of 42000 km in
a circular orbit. It completes one revolution in 24 hours.
Calculate its linear speed.
a. 10990 kmph
b. 10890 kmph
C: 11000 kmph
d. 11880 kmph​

Answer 1

Answer:

3.05km s^-1

Explanation:

s=2×3.14.r

S=2×3.14×42000=263,760

then linear speed is 263,760÷24×60×60=3.05kms^-1
