A body weighing 2 kg is at a height of 10 meters and has a speed of 10 meters per second.

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
