1. The problem statement, all variables and given/known data The Force is F(x)=Av2/x. find x(t) if x(0)=0 and vx(0)=0 2. Relevant equations 3. The attempt at a solution My issue is that i set this up as mdv/dt=F but when i try to separate the variables i don't know what to do about the v since it depends on x. any suggestions?
