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
The spring's work output while it is not extended is 5 J.
<h3>What is The Hooke's law ?</h3>
According to Hooke's law, as long as the elastic limit is not exceeded, the extension of a particular material is directly proportional to the force applied. Hence, we must be aware of that F = Ke
F = Applied force
Force constant is K.
Extension = e
F = applied force
Force constant is K.
Extension = e
Using the graph
K = F/e
F = 200N
E equals 5 cm or 5 * 10-2 m
K = 200N/ 5 * 10^-2 m
K = 4000 N/m
Now;
Work = 1/2Ke^2
Work = 0.5 * 4000 N/m * (5 * 10^-2 m)^2
Work = 5 J

Answer:
98 kg
Mass is given as 10 kg. Therefore, Weight = 10 kg * 9.8 m/s^2. Weight = 98 kg.m/s^2. = 98 Newtons.
