1. The problem statement, all variables and given/known data Hey all. I have F(v) and I'm looking for x(t). F(v) = -bV2 I'm a physics undergrad student who hasn't done diff. equations in a while, so I'm very unsure of my work so far... but here it is. 3. The attempt at a solution I write F=ma as F(v)=mdv/dt: -bV2=mdv/dt -m∫ dv/v2 = -b ∫dt -m/v = -bt m/v = bt v = m/bt = dx/dt ∫ dx = m/b ∫ dt/t Finally x(t) = m/b*ln(t) Does this look good?
