The body is raised to a height of 3 meters for 5 minutes. To lift this body requires a power of 0.1 watts. Determine body weight.

To find the mass of the lifted body, we will use the formula: N = A / t = m * g * h / t, whence we express: m = N * t / (g * h).

Variables and constants: N – required power (N = 0.1 W); t is the duration of lifting the body (t = 5 min = 300 s); g – acceleration due to gravity (g ≈ 10 m / s2); h – height (h = 3 m).

Calculation: m = N * t / (g * h) = 0.1 * 300 / (10 * 3) = 1 kg.

Answer: The mass of the lifted body is 1 kg.
