NDsolve diferencial equation problem – Mathematica Stack Exchange

I am trying to solve a differential equation using NDsolve, but I keep getting this error message :(NDSolve::ndnum Encountered non-numerical value for a derivative at t == 0);

This is the equation :NDSolve({0.000064 v'(t) == (3/4 1000/(980 0.005) 0.000064 (24*((1 + 0.15 ((v(t) 0.005)/(8.910^-4))^0.687)/((v(t) 0.005)/(8.910^-4))) v(t)*v(t)) – (0.000064 9.8 (1 – 1000/980))), v(0) == 0.01}, v, {t, 0, 3})

Does anyone have suggestions on how can I solve it?
