How much work does the climber do on his pack if his pack weighs 90 N and he climbs to a height of 30 m?
1 answer:
Answer: Option D) 2,700 Joules
Explanation:
Work is done when the force is applied in a specific direction. It is measured in joules. Thus, Workdone is the product of force and distance
Workdone = Force X Distance
Force = 90Newton
Distance = 30 metres
Workdone = 90N X 30m
Workdone = 2700 joules
The climber does work of 2,700 joules
