Answer:
Potential energy, PE = 2.94 joules
Explanation:
Given that,
Mass, m = 0.3 kg
It is placed at a height of, h = 1 m
We need to find the gravitational potential energy of the book. It is given by :
PE = mgh
[tex]PE=0.3\ kg\times 9.8\ m/s^2\times 1\ m[/tex]
PE = 2.94 Joules
So, the potential energy of the book at this height is 2.94 Joules. Hence, this is the required solution.
