How does the potential energy of a person weighing 50 kilograms change when ascending

How does the potential energy of a person weighing 50 kilograms change when ascending in a balloon to a height of 100 meters.

Given:

m = 50 kilograms – the mass of a person;

h = 100 meters – the height to which the person climbed in the balloon;

g = 10 Newton / kilogram – acceleration of gravity (approximate value).

It is required to determine E (sweat) – how the potential energy of a person will change when he rises to a height h.

At the surface of the earth, the potential energy of a person is zero. Then, to determine the change in potential energy, you must use the following formula:

E (sweat) = m * g * h;

E (pot) = 50 * 100 * 10 = 500 * 100 = 50,000 Joules (50 kJ).

Answer: when a person rises to a height of 100 meters, his potential energy will change by 50,000 Joules (50 kJ).



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
