An artificial satellite is moving in a circular orbit of radius 36,000 km. Calculate its speed if it takes 24 hours to revolve around the earth.
The radius of the orbit, r = 36000 km Distance traveled by satellite to complete one orbit = circumference of the orbit Circumference = 2πr = 2×227×36000 = 226285.7 km Step 2, Finding the linear velocity We have, Time, t = 24 hr We know, The linear velocity of satellite = DistanceTime Putting all the values Linear velocity =226285.724 After solving Velocity = 9428.57 km/h Hence the linear velocity of the satellite is 9428.57 km/h
