Determine the total mechanical energy of a parachutist whose mass is 80 kg, at the time of the passage of wine

Determine the total mechanical energy of a parachutist whose mass is 80 kg, at the time of the passage of wine he is booted to an altitude of 500 m and collapses with a speed of 2 m / s.

These tasks: m (weight of the parachutist in question) = 80 kg; h (the height at which the parachutist is) = 500 m; V (speed of movement) = 2 m / s.

Constants: g (acceleration of gravity, acceleration of a parachutist) ≈ 10 m / s2.

The total mechanical energy of the parachutist can be calculated by the formula: Ecomplete = En + Ek = m * g * h + 0.5 * m * V ^ 2.

Calculation: Epoln = 80 * 10 * 500 + 0.5 * 80 * 2 ^ 2 = 400 160 J.

Answer: The parachutist in question has a total mechanical energy equal to 400 160 J.
