How many joules of potential energy does a 1-kg book gain when it is elevated 4 m? When it is elevated 8 m? (Let

Potential energy gained by book.
Answer to Problem 38A
Potential energy gained by book 40 J and 80 J
Explanation of Solution
Given :
Mass of the book,
Height is given,
Acceleration due to gravity,
Formula used :
Potential energy is given by,
Where, m is mass, g is acceleration due to gravity and h is height.
Calculation :
Now, substituting the value of m , g and
For,
Conclusion :
Therefore, potential energy gained by book is 40 J when elevation is 4 m and potential energy is 80 J when height is 8 .
