calculate potential energy of a person having 60 kg mass on the Summit of of Mount Everest height of Mount Everest is 8848 metres from sea level. (g=9.8m/s2)
a. 5202624 joule
b. 25 j
c. 19.7 j
d. 202624 j
Answers
we know that,
m= 60kg
h= 8848m
g= 9.8ms-2
potential energy = mgh
=60×8848×9.8
= 5202624 Joule
a) is the answer 5202624 Joule
Given,
Mass of a person = 60 Kg
Height of the summit of Mount Everest from the sea level = 8848 meters
Acceleration due to gravity = g = 9.8m/s^2
To find,
The potential energy of the person on the summit of Mount Everest.
Solution,
We can simply solve this numerical problem by using the following process:
Mathematically,
The total potential energy of an object = (mass of the object) × (height of the object) × (acceleration due to gravity)
Now, according to the question;
The potential energy of the person on the summit of the Mount Everest
= (mass of the person) × (height of the summit of Mount Everest) × (acceleration due to gravity)
= 60 Kg × 8848 meters × 9.8m/s^2
= 52,02,624 Kgm^2/s^2
= 52,02,624 N.m
= 52,02,624 Joules
Hence, the total potential energy of the person on the summit of Mount Everest is equal to 52,02,624 Joules. (Option-A)
