Answer: 9496200 joules
Explanation:
Gravitational potential energy, GPE is the energy possessed by the moving plane since it moves against gravity.
Thus, GPE = Mass m x Acceleration due to gravity g x Height h
Since Mass = 1900kg
g = 9.8m/s^2
h = 510 metres (units of height is metres)
Thus, GPE = 1900kg x 9.8m/s^2 x 510m
GPE = 9496200 joules
Thus, the gravitational potential energy of the airplane is 9496200 joules
