Step 1
We know that the altitude is 200 km, so the radius is the sum of the radius of Mars (3389.5 km) and the altitude: r = 3389.5 km + 200 km = 3589.5 km Show more…

A satellite is placed in a circular orbit to observe the surface of Mars from an altitude of 144 km. The equatorial radius of Mars is 3397 km. If the speed of the satellite is 3480 m/s. a. what is the magnitude of the centripetal acceleration of the satellite.

A satellite is in a circular orbit 600 km above the Earth's surface. The acceleration of gravity is 8.21 m/s2 at this altitude. The radius of the Earth is 6,400 km. Determine the speed of the satellite, and the time to complete one orbit around the Earth.
