A 800N mountain climber scales a 160m cliff. How much work is done by the mountain climber?
Fittoniya [83]

Answer:

Work done, W = 128 kJ

Explanation:

Given that,

Weight of a mountain climber, F = 800 N

It climbs to a cliff that is 160 m high.

We need to find the work done by the mountain climber. The work done by an object is given by the formula as follows :

W = Fd

Put the values of F and d.

W = 800 N × 160 m

W = 128000 J

or

W = 128 kJ

So, 128 kJ of work is done by the mountain climber.
