2. Planet Alpha Omega has a mass of 2.75 x 1025 kg and a diameter of 20,300 km. Calculate the orbital period AND the velocity for a satellite orbiting the planet at an altitude of 720. km above the surface of the planet.
Orbital period [sec] =
Velocity [m/s] =
3. A satellite is orbiting Earth at an altitude of 1,830 km above Earth's surface. Calculate the orbital period
AND the velocity of the satellite.
Period [sec] =
velocity [m/s] =
4. A rock is tied to the end of a string and spun in a circle. The string is 1.80 m long; the rock spins with a
centripetal acceleration of 9.40 m/s2. Calculate the period of revolution (T) of the rock.
