Question

An artificial Satellite is moving in a circular orbit of radius 36,000km. If it takes 24 hours to complete one orbit around the earth, find its linear speed .
Please experts solve this ASAP..!!!!

Answer 1

SOLUTION :- 

Radius of orbit , r = 36,000 Km

Distance travelled by satellite to complete one orbit = circumference of the orbit = 2πr

= 2 × 22/7 × 36,000 = 226285.7 km

Time , t = 24 hr

therefore, Linear velocity of satellite = Distance / Time 

= 226285.7 km/ 24h 

= 9428.57 Km h ^ -1

= 9428.57 / 3600 

= 2.62 km s ^ -1
