A plane is in level flight at constant speed and each of its two wings has an area of

40 \mathrm{~m}^2

. If the speed of the air is

180 \mathrm{~km} / \mathrm{h}

over the lower wing surface and

252 \mathrm{~km} / \mathrm{h}

over the upper wing surface, the mass of the plane is ___________ kg. (Take air density to be

1 \mathrm{~kg} \mathrm{~m}^{-3}

and
