Question

Calculate how much gravitational potential energy is lost by an
aircraft of mass 80 000 kg if it descends from an altitude of 10
000 m to an altitude of 1000 m. What happens to this energy if
the pilot keeps the aircraft's speed constant?​

Answer 1

Answer:

2 x 10^8

Explanation:

change in pot ene = mgr1-mgr2

80000 x 10 x 10^4 - 80000 x 10 x 10^3 = 2 x 10^8
