Question: A good approximation to gravity above the surface of the Earth is g = 9.81 - 3.32 Ã 10-6h m/s2, where h is the distance

A good approximation to gravity above the surface of the Earth is g = 9.81 - 3.32 Ã— 10-6h m/s2, where h is the distance above the Earth's surface in meters. The commercial airplane in Fig. 1.23, with a mass of 140 000 kg, flies at a height of 10 km above the Earth's surface. Calculate its weight on the Earth's surface and at 10 km. Also calculate its potential energy at 10 km.
