| **A body weighing 2 kg is at a height of 10 meters and has a speed of 10 meters per second. Determine the total mechanical energy of the body.**

Let’s remember that the total mechanical energy is equal to the total potential and kinetic energy.

Then

W = Ep + Ek = mgh + m * v ^ 2/2 = 200 + 100 = 300J

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.
