Answer :
Final answer:
The gravitational potential energy of a 100kg skydiver jumping from 4000 meters is 3,920,000 joules.
Explanation:
The gravitational potential energy of an object can be calculated using the formula:
Gravitational potential energy = mass × acceleration due to gravity × height
In this case, the mass of the skydiver is 100 kg, the acceleration due to gravity is approximately 9.8 m/s², and the height is 4000 meters. Plugging in these values into the formula:
Gravitational potential energy = 100 kg × 9.8 m/s² × 4000 meters = 3,920,000 joules
Therefore, the skydiver has 3,920,000 joules of gravitational potential energy when they jump from 4000 meters.
