A satellite, mass of satellite=5850 kg, is in circular orbit of 4.1x10^5m above the surface of a planet, which has a radius of 4.15x10^6m. The period for the orbit is 2 hours. A) calculate the tangential velocity of the satellite. B) find the mass of the planet. C) how much would the satellite weigh on the surface of the planet? I have only been able to fint the tang-velocity. v = √(GM / R ) = √(6.67 x 10-8 x 5850 / 4.1 x 105 ) m/s Can anyone solve part B and C?
