The climber climbed in the mountains to a height of 2.5 km. Determine the mechanical work performed by the climber during the ascent if his weight with equipment is 72 kg.
To solve the problem, you need to perform a unit conversion.
2.5 km = 2500 m.
To find a job, you need to use the formula A = mgh.
m – mass, g – gravitational acceleration, h – height.
A = 72kg * 9.8 m / s2 * 2500m
A = 1764000 J = 1.764 MJ.
Answer: work = 1.764MJ.
