satellite question. find mass of planet and weight on planet?
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?

mrw^2=GMm/r^2 manipulate the v=rw and w=2pi/period

For both cases equate centripetal force with gravitational force and you you be able to get the answer.
