Problem with Physics!! Need help please

Posted on 2014-11-17 05:22:00 in Physics by CHRIS

Air (density 1.29kg/m^3) passes over the top and bottom surface of an aircraft whose effective wing surface is 75.5m^2, at 954 km/h. If air speed beneath the wings is 540 km/h, and the lift force due to the Bernoulli effect is all the fore necessary to keep the plane in the air, what is the mass of the plane? please show work.
