Re: How does SMAC determine the DeltaV and PDOF?

After responding to a recent question on determining DeltaV from acceleration I realized this thread should also include some fundamentals on integration to determine velocity and displacement. I did a quick search of the internet and here is an example of some related notes: Finding Velocity and Di...

Re: What is the appropriate rotating vehicle % drag factor?

Q:Thanks for the info. I guess I should have provided more information on the crash. The vehicle in question completed a straight skid and struck the area of the rear axle of a box truck that was in the process of a left turn. The rotation was initiated because of this impact not due to oversteering...
