Planckenstein Posted January 21, 2020 Report Share Posted January 21, 2020 Say I have an aircraft. I know it's thrust and the properties needed to determine its drag. The craft accelerates at at 10 m/s^2. Making the drag equal to the thrust, I determine its max speed to be 180 m/s. If I were to ignore drag, I could simply say it would take 18 seconds to reach maximum velocity, but I am attempting to determine how long it would take to reach 180 m/s including drag. As the velocity increases, the drag force with increase exponentially, so the net thrust/rate of acceleration would decrease each second. Is there a way to wrap F=ma with F=(CApv^2)/2 to determine the time to reach maximum velocity including drag or do I need to learn some calculus for this one?
