Determine the total mechanical energy (A) of a body weighing 6 kg (m), located at a height of 9 (h)

Determine the total mechanical energy (A) of a body weighing 6 kg (m), located at a height of 9 (h), moving at a speed of 17 m / s (v).

Task data: m (body weight) = 6 kg; h (height at which the body under consideration is located) = 9 m; V (speed of movement) = 17 m / s.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

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

Let’s perform the calculation: Епол. = 0.5 * 6 * 17 ^ 2 + 6 * 10 * 9 = 867 + 540 = 1407 J.

Answer: The total mechanical energy of the body in question is 1407 J.
