| **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.
