Answer :
Answer:
90 kJ
Explanation:
Work = force × distance
W = (900 N) (100 m)
W = 90,000 J
W = 90 kJ
The amount of work done by the mountain climber is 90000 Joules.
To calculate the work done by the mountain climber, we use the formula below.
Formula:
- W = fd
Where:
- W = work done by the mountain climber
- f = Weight of the mountain climber
- d = Height of the cliff
From the question,
Given:
- f = 900 N
- d = 100 m
Substitute these values into equation 1
- W = 900(100)
- W = 90000 Joules
Hence, the amount of work done by the mountain climber is 90000 Joules.
