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:
Answer:
potential energy of the luggage is 196J
