Question
A person lifts a piece of luggage of 10 kg at the height of 2 m above the ground. What is the potential energy possessed by the luggage?
- 180 J
- 196 J
- 20 J
- 10 J
Hint:
Potential energy can be calculated by the mgh
The correct answer is: 196 J
Given:
Mass of the luggage (m) = 10kg
Height (h) = 2m
Acceleration due to gravity (g) = 9.8ms-2
To find:
Potential energy =?
Solution:
![P o t e n t i a l space e n e r g y space equals space m g h space
P E space equals space 10 space cross times 9.8 space cross times 2 space
P E space equals space 196 J space](data:image/png;base64,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)
