The climber climbed in the mountains to a height of 2 km. Determine the mechanical work done by the climber

The climber climbed in the mountains to a height of 2 km. Determine the mechanical work done by the climber during the ascent if his weight with equipment is 85 kg.

To find the amount of mechanical work performed by the specified climber, apply the formula: A = ΔEp = ma * g * h.

Constants and variables: ma – weight of the specified climber with equipment (ma = 85 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h – change in the height of the climber (h = 2 km = 2 * 103 m).

Calculation: A = ma * g * h = 85 * 10 * 2 * 10 ^ 3 = 1.7 * 10 ^ 6 J.

Answer: The mechanical work performed by the specified climber is 1.7 MJ.
