Hallsofivy,
i solved for k, the drag force is kv^2 which i equated it to Newton's second law Mass*acceleration. Then solving for acceleration resulted in k*v^2/(5000kg). then I integrated the relevant equation vdv=ads to solve for ds. The confusion lies in the calculated...

tom mattson,
Newton's second law is f=m*a. ma=kv^2. therefore a=(kv^2)/m. This is where the relevant equation that i cited could be used, where the acceleration is calculated and velocity is given which then leaves you with the unknown term delta x. I am stuck on what velocity would i use to...
