Question

A satellite revolves around earth it completes one round in 24hrs. its orbit is 36000km away from earth . find distance and displacement travelled by the satellite within 36hrs.

Answer 1

the speed of an object moving in a circular orbit is given by the formula
s=2
$2\pi \times r \div t$
radius=42250 km
time =34 hrs
$speed = 2 \times 22 \times 42250 \div 7 \times 24$
$= 11065.4 \: km \div hr$
