Hey. I was not sure if I could post this somewhere else, since this has nothing to do with homework or anything like that. 1. The problem statement, all variables and given/known data In a newtonian world: Determine the position of object two, being x, z spatial coordinates and y a time one relative to object 1. Object 1 is (0; y; 0). The objects are at d distance of course. The colision of the objects can be ignored. Also "o2" is moving at v m/s in the same directon as the vectour (0;1;0). For the sake of simplicity I'll give the variables values. "O1"(0; y; 0) "02"( 0; 0; 10^10) d=10^10 "M1"=10^7 "M2"=10^7 (not sure if this matters but oh well...) v=10^3 m/s 2. Relevant equations f=[("M1"+"M2")/d^2]*6,67*10^-11 a=f/M Being: a(m/s/s)=acceleration f(N)=force M(kg)=mass d(m)=distance v(m/s)=speed "M1"(kg)=mass of object one "M2"(kg)=mass of object two "O1"=object one "O2"=object two 3. The attempt at a solution (not) This problem would require a bit of time for me to solve, because I'd have to come up with some formulas on my own. Everytime I sit down to try this I get distracted. So I hope someone could show me the deduction of the formula that gives the position of "O2". Something like f(y)="O2"(x, y, z) Thank you PS:In case I forgot to add some info tell me.
