How will the potential energy of a person weighing 50 kg change when ascending in a balloon to a height of 100 m?
| August 5, 2021 | education
The change in the potential energy of a person during ascent in a balloon is calculated by the formula:
Ep = m * g * (h1 – h2), where m is the mass of a person (m = 50 kg), g is the acceleration of gravity (g = 10 m / s2), h1 – h2 is the change in the height of a person above the zero level, height ascent of the ball (h1 – h2 = 100 m).
The change in the potential energy of a person is equal to:
Ep = m * g * (h1 – h2) = 50 * 10 * 100 = 50,000 J = 50 kJ.
Answer: The potential energy of a person will increase by 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.
