Phobos, a moon of the planet Mars, whose orbital radius is 9380 km and its orbital period I (2.77 x 104 seconds). Determine the mass of Mars based on this data. (Where: G = 6.67 x 10-11).
6.37 x 10 power (23) Kg
1.36 x 10 power (15 ) kg
9.21 x 10 power ( 34 ) Kg
3.23 x 10 power ( 27 ) kg
If the satellite orbit the earth in an orbit if after ¼ revolution the displacement moved by the sataliite is 1000 m find the orbital velocity of the satellite given that ( the mass of the earth is 5.6 x 1024 Kg – G = 6.67 x 10-11 _ R earth = 6360 Km )
