Homework Equations
Not too sure to be honest.
The Attempt at a Solution
Well, r1 cross product m v1 = r2 cross m v2
But, there is a force applied so I have to take that into account.
I was thinking,
The moment of momentum after the thrust = Moment of momentum when it first enters the second orbit
r1 m v1 = r1 m v2
gives
v2/v1 = 7
But I am not being able to take that any further.
I'm trying to use energy relations but it gives me an equation in terms of GM (gravitational constant and mass of planet).
I have no idea where to begin. Maybe you guys could point me to the right direction?
