Question

Альпинист поднялся в горах на высоту 2 километра. определите механическую работу совершенную альпинистом при подъеме если его масса вместе со снаряжением равна 85 килограммов

Answer 1

A=F*S В системе си S=2000 м 
F=m*G= 9,8*85=833H
A= 833*2000= 1666 kДж

Answer 2

Calculation of Mechanical Work

To determine the mechanical work done by the climber during the ascent, we need to calculate the work done against gravity. The formula for calculating work is:

Work = Force x Distance

In this case, the force is equal to the weight of the climber and their equipment, and the distance is the height of the ascent.

The weight of the climber and their equipment can be calculated using the formula:

Weight = Mass x Gravity

Given that the mass of the climber and their equipment is 85 kilograms, and the acceleration due to gravity is approximately 9.8 meters per second squared, we can calculate the weight:

Weight = 85 kg x 9.8 m/s^2

Now, we can calculate the work done by the climber:

Work = Weight x Distance

The distance is given as 2 kilometers, but we need to convert it to meters:

Distance = 2 km x 1000 m/km

Now we can substitute the values into the formula:

Work = (85 kg x 9.8 m/s^2) x (2 km x 1000 m/km)

Calculating this expression will give us the mechanical work done by the climber during the ascent.
