Answer:
Explanation:
Potential energy is the energy of a body due to is virtue of rest.
Potential energy is given as mgh
g is a constant and it is 9.81m/s²
And also the mass of the body is given as 1.3kg
Now the height of the body is
He took a book to a storey building of height 26m
He still holds the book 151 cm (1.51m) above the house.
The house is on an altitude of 1609m from the sea level.
Total Ug with out the sea level is
Ug=mgh
Ug=1.3 × 9.81 ×(26+1.51)
Ug=350.84J
Then, the potential energy due to the sea level is given as
Ug=mgh
Where g = 1/6371 m/s²
Therefore
Ug=mgh
Ug=1.3 × 1/6371 ×1609
Ug=0.328J
Total energy = 0.328+350.84
Ug=351.17J
The gravitational potential energy Ug of the book is 351.17J
We know that
Potential energy = mgh
here
g is a constant and it is 9.81m/s²
And also the mass of the body = 1.3kg
Now
Ug=mgh
Ug=1.3 × 9.81 ×(26+1.51)
Ug=350.84J
So, the potential energy because of the sea level is
Ug=mgh
Where g = 1/6371 m/s²
Ug=1.3 × 1/6371 ×1609
Ug=0.328J
So,
Total energy = 0.328+350.84
Ug=351.17J
