Quenstion about netwonian mechanics.
We have a small body that is moving against a very massive object with big density.
For a given time t i want to know what can be the maximum distance of this object.
So we have the mass of the big object M , the mass of the small m with speed Ua and the time t.
the velocity at any moment is Ua+Uf where Uf is the speed because of the acceleration of the gravity.
F=M*m*G/r^2
d(dr/dt)/dt=a
where a is the acceleration
a=M*G/r^2
r=R+s where R is the radius of the object and s the distance tha the object traveled at time t. I need an equation to find the s.
Dont forget that the object begins with a speed Ua not from 0 speed.
thanks and please quick
Of course the gravity force is not constant but change with distance,
