Gravitation!

A satellite revolve round a planet of radius R at t=0, and in an orbit of radius ηR.Due to change in weather;atmospheric density increases and satellite experiences a resistance force which depends on the velocity of satellite as f=αv^{2}where α is a constant .FInd the time after which the satellite will hit the surface of planet.Assume that the planet doesn't moves during motion of the satellite relative to the planet.
