static air pressure equals to 1.23 * 9.81 * 1100m . Am I rite?? but the answer is wrong if I use this value...

I have solve till Velocity but not V(max). my eqn is Power= drag coeff * 1/2 * Area * density* velocity^3 to find V(max),what should I set to zero and then differentiate?? ??

yes,but how to get p1 and p2 ??

Hi, A vehicle land on a mountain of 4400ft.The Engine delivers 400hp to the wheels and careful streamlining has resulted in a drag coefficient of 0.5,based on a 20ft^2 frontal area.Compute the maximum ground speed of the car in i)still air and ii)with a 20mph head wind for part i)I have...

Hi, velocity of air=0, an airfoil or wing with is moving forwards with a velocity of 40m/s at an altitude of 1100m. At a certain point close to the wing (which is a point on top of the wing) ,the air speed relative to the wing is 50m/s.Find the pressure at that point. Somebody pls help...
