Homework Statement
Assume we have some mass, m, that varies it's distance as v(x)=1/x^2. Assume v(x=0)=0 at t=0.
What is the force F(x) that causes this motion?
Find x(t).
What is F(t)?
Homework Equations
[tex]F=m\ddot{x}[/tex]
The Attempt at a Solution
I think I need to take the derivative of my velocity with respect to x to find my acceleration. With that I can find the force as a function of x? I think this may be wrong, but I'm really not sure. Could someone help me out as to where to begin?
